Do While Loop Need Help Fast!!!

Im trying to set this do while loop in my code and it keeps giving me an error .

Code:

#include <stdio.h>
#define interest = .02	
int main ()

{
    int date, choice, option1, option2;
	double amt, balance= 2000.00;

	do{
			
			printf(" Welcome to Moon Trust Bank!\n\n");
			printf(" Please Choose From The Following Options.\n\n");
			printf("   1)  Deposit Funds (Credit Transaction)\n");
			printf("   2) Withdraw Funds ( Debit Transaction)\n");
			printf("   3) Print Statement of Account\n"); 
			printf("   4) Compute Interest and Exit the Program\n");
	
			scanf("%d", &choice);
	
	if (choice == 1)
	
			{
				printf("Your current balance is $%.2f.\n", balance);
				printf("Please enter the date.\n");
				scanf("%d", &date);
				
				printf("Please enter the amount you wish to deposit into your account.\n");
				scanf("%lf", &amt);
				
				balance = balance + amt;
				
				printf("Your current balance is $%.2f.\n\n", balance);		

			}
	
	else if (choice == 2)
	
			{
				printf("Your current balance is $%.2f.\n", balance);
				printf("Please enter the date.\n");
				scanf("%d", &date);
				
				printf("Please enter the amount you wish to withdraw from your account.\n");
				scanf("%lf", &amt);
					
						if (amt > balance)
								{
									printf(" Please enter a smaller amount, funds not sufficient!\n");
									scanf("%lf", &amt);
								}
				
				balance = balance - amt;
				
				printf("Your current balance is $%.2f.\n\n", balance);
				}
	
	else if (choice == 3)
	
			{
				printf("Your current balance is $%.2f.\n", balance);
				printf("Please enter the date.\n");
				scanf("%d\n\n", &date);
				
				printf("So far this month:\n");
				printf("Your current balance is $%.2f.\n", balance);				
				printf("Your total number of credit transactions are %d\n", option1);
				printf("Your total number of debit transactions are %d\n", option2);
			}
	
	
		}
	
	
	while (choice == 4)
		{
			printf("Statement of Account for October, 2004\n\n");
			printf("Your total number of credit transactions are %d\n", option1);
			printf("Your total number of debit transactions are %d\n", option2);
			printf("Interest Computed: $%.2lf\n", interest);
			printf("Final Balance: $%.2lf\n\n", balance);
			printf("Good Bye!");
                  return 0;
                      }

it says i have a parse error before "{" its the one right up under where the "while" loop starts. Im not done with my equations (ex. intrest) so you dont have to pay that any attention i just need to have the do while loop format right.

Well, you started a do-while loop up top. How about finishing that one some place? That'd be a good start. Also, count your { } pairs and you'll see you've got some other problems. Good indentation helps. Yours is what we call "not good".

Quzah.

What about my indentations now? Can you see what the problem is?

Code:

#include <stdio.h>
#define interest = .02	
int main ()

{
    int date, choice, option1, option2;
	double amt, balance= 2000.00;

	do
			{
					printf(" Welcome to Moon Trust Bank!\n\n");
					printf(" Please Choose From The Following Options.\n\n");
					printf("   1)  Deposit Funds (Credit Transaction)\n");
					printf("   2) Withdraw Funds ( Debit Transaction)\n");
					printf("   3) Print Statement of Account\n"); 
					printf("   4) Compute Interest and Exit the Program\n");
					scanf("%d", &choice);
	
										if (choice == 1)
	
												{
														printf("Your current balance is $%.2f.\n", balance);
														printf("Please enter the date.\n");
														scanf("%d", &date);
				
														printf("Please enter the amount you wish to deposit into your account.\n");
														scanf("%lf", &amt);
				
														balance = balance + amt;
				
														printf("Your current balance is $%.2f.\n\n", balance);		

												}
	
										
										else if (choice == 2)
	
												{
														printf("Your current balance is $%.2f.\n", balance);
														printf("Please enter the date.\n");
														scanf("%d", &date);
				
														printf("Please enter the amount you wish to withdraw from your account.\n");
														scanf("%lf", &amt);
					
															if (amt > balance)
																{
																	printf(" Please enter a smaller amount, funds not sufficient!\n");
																	scanf("%lf", &amt);
																}
				
														balance = balance - amt;
				
														printf("Your current balance is $%.2f.\n\n", balance);
												}
	
										else if (choice == 3)
	
												{
														printf("Your current balance is $%.2f.\n", balance);
														printf("Please enter the date.\n");
														scanf("%d\n\n", &date);
				
														printf("So far this month:\n");
														printf("Your current balance is $%.2f.\n", balance);				
														printf("Your total number of credit transactions are %d\n", option1);
														printf("Your total number of debit transactions are %d\n", option2);
												}
	
	
			}
	
			
									while (choice == 4)
												{
														printf("Statement of Account for October, 2004\n\n");/*
														printf("Your total number of credit transactions are %d\n", option1);
														printf("Your total number of debit transactions are %d\n", option2);
														printf("Interest Computed: $%.2lf\n", interest);
														printf("Final Balance: $%.2lf\n\n", balance);
														printf("Good Bye!");*/
			
														return 0;
												}
			
			
}

Identation is still not good...After a conditional (if, while) the code should be tabbed over ONCE. The brackets should be the same indentation as the conditional...like so

Code:

while(true)
{
    do some stuff
    do some more stuff
    if (more stuff)
    {
        more more more
    }
}

I am not scrolling horizontally to read anything

For forum posting, replace each tab with four spaces. That seems to work well.

HOW ABOUT THIS?

Code:

#include <stdio.h>
#define interest = .02	
int main ()

{
    int date, choice, option1, option2;
	double amt, balance= 2000.00;

	do{
	
		printf(" Welcome to Moon Trust Bank!\n\n");
		printf(" Please Choose From The Following Options.\n\n");
		printf("   1)  Deposit Funds (Credit Transaction)\n");
		printf("   2) Withdraw Funds ( Debit Transaction)\n");
		printf("   3) Print Statement of Account\n"); 
		printf("   4) Compute Interest and Exit the Program\n");
		scanf("%d", &choice);
	
			if (choice == 1)
            	{
				printf("Your current balance is $%.2f.\n", balance);
				printf("Please enter the date.\n");
				scanf("%d", &date);
				printf("Please enter the amount you wish to deposit into your account.\n");
				scanf("%lf", &amt);
				
				balance = balance + amt;
				
				printf("Your current balance is $%.2f.\n\n", balance);		

				}
	
										
			else if (choice == 2)	
				{
				printf("Your current balance is $%.2f.\n", balance);
				printf("Please enter the date.\n");
				scanf("%d", &date);
				
				printf("Please enter the amount you wish to withdraw from your account.\n");
				scanf("%lf", &amt);
					
				if (amt > balance)
					{
					printf(" Please enter a smaller amount, funds not sufficient!\n");
					scanf("%lf", &amt);
					}
				
				balance = balance - amt;
				
				printf("Your current balance is $%.2f.\n\n", balance);
					}
	
			else if (choice == 3)
					{
					printf("Your current balance is $%.2f.\n", balance);
					printf("Please enter the date.\n");
					scanf("%d\n\n", &date);
					printf("So far this month:\n");
					printf("Your current balance is $%.2f.\n", balance);				
					printf("Your total number of credit transactions are %d\n", option1);
					printf("Your total number of debit transactions are %d\n", option2);
					}
	
	
			}	
			
			while (choice == 4)
					{
					printf("Statement of Account for October, 2004\n\n");/*
					printf("Your total number of credit transactions are %d\n", option1);
					printf("Your total number of debit transactions are %d\n", option2);
					printf("Interest Computed: $%.2lf\n", interest);
					printf("Final Balance: $%.2lf\n\n", balance);
					printf("Good Bye!");*/
					return 0;
					}
			
			
}

You're still not getting it...

Code:

#include <stdio.h>
#define interest = .02
int main ()
{
    int date, choice, option1, option2;
    double amt, balance= 2000.00;

    do{
        printf(" Welcome to Moon Trust Bank!\n\n");
        printf(" Please Choose From The Following Options.\n\n");
        printf("   1)  Deposit Funds (Credit Transaction)\n");
        printf("   2) Withdraw Funds ( Debit Transaction)\n");
        printf("   3) Print Statement of Account\n"); 
        printf("   4) Compute Interest and Exit the Program\n");
        scanf("%d", &choice);
        if (choice == 1){
            printf("Your current balance is $%.2f.\n", balance);
            printf("Please enter the date.\n");
            scanf("%d", &date);
            printf("Please enter the amount you wish to deposit into your account.\n");
            scanf("%lf", &amt);
            balance = balance + amt;
            printf("Your current balance is $%.2f.\n\n", balance);
        }
        else if (choice == 2){
            printf("Your current balance is $%.2f.\n", balance);
            printf("Please enter the date.\n");
            scanf("%d", &date);
            printf("Please enter the amount you wish to withdraw from your account.\n");
            scanf("%lf", &amt);
            if (amt > balance){
                printf(" Please enter a smaller amount, funds not sufficient!\n");
                scanf("%lf", &amt);
            }
            balance = balance - amt;
            printf("Your current balance is $%.2f.\n\n", balance);
        }
        else if (choice == 3){
            printf("Your current balance is $%.2f.\n", balance);
            printf("Please enter the date.\n");
            scanf("%d\n\n", &date);
            printf("So far this month:\n");
            printf("Your current balance is $%.2f.\n", balance);
            printf("Your total number of credit transactions are %d\n", option1);
            printf("Your total number of debit transactions are %d\n", option2);
        }
    }
    while (choice == 4)//here's your problem... does the while belong to the do-while, or it's alone??
    {
        printf("Statement of Account for October, 2004\n\n");
        printf("Your total number of credit transactions are %d\n", option1);
        printf("Your total number of debit transactions are %d\n", option2);
        printf("Interest Computed: $%.2lf\n", interest);
        printf("Final Balance: $%.2lf\n\n", balance);
        printf("Good Bye!");
        return 0;
    }
//end bracket missing

Now that the code IS correctly idented try to understand it

the 'do' does not have a 'while'

"xErath" The While does belong to the do-while.

Someone Please Help Me!!!!!

2 spaces works better. I dislike the default 4 spaces in MSVC and MSVC.net. Also 4 spaces on the board tends to make it into like 8 spaces, even with tabs not being inserted.

Make sure in your options you have your compiler set to actually insert spaces instead of tabs and that should fix your posting problem, although not all of them. Best way to transfer code from the dev environment to the board is to copy the code, paste into notepad, manually touch it up, copy, and paste in reply window on the board. Seems to work just fine.

As for your other problems...well your main function is just too doggone big. Try to follow this rule. One function=one task. One function should do one task and do it well. When you have one function doing a billion things it quickly becomes impossible to debug your code because you will be lost and, as evidenced by this thread, others will too.

Ok, Mack, what your missing is that when you place a do...while(), the while at the end of the do ends the loop. What you have is a while inside a do..while, and the do...while doesn't have a while.

a do...while looks like this...

Code:

do {
    some suff
    some more stuff
} while (true);

What you have is

Code:

do {
    some stuff
    some stuff
    while (choice == 4) {
        some stuff
    }
} while(true);

Instead, you have a while, which itself has a block of code. This means that your do does not have a closing while.

Your missing whats in red.

I hope thats clearer...

SEE!? It's as I said:
1) COUNT YOUR { } PAIRS! If you had actually listened to me, you'd be done by now.
2) Look at your do-while loop.

a) You either have a correct do-while loop, in which case, the last pair of braces is pointless.

b) You are missing a while loop.

It's one or the other. Make up your mind. Also, try listening to what people have been telling you. What's the point of asking for help if you aren't going to pay attention to it?

...
Don't mock me. I know that well. You seem not to know what a while is.
EDIT:
The choice == 4 statment should be in another if inside the do-while, and it you be easier to have a while(1){}.

5 seconds were enough to spare us all time...
Mackology next time please make some effort trying to understand what you're doing.
