    can't figure it out HELP

    Was assigned a homework ass. And the teacher and book are not to helpfull.

    I am supposed to determine if a store customer has exceeded the credit limit on his charge account. For each customer the facts are available. Account number, balance at the beginning of the mounth, total of all item charged by customer this month, total of all credits applied to customer's account this month, and allowed credit limit.
    We have studied the if, if-else and while strutures only, can any one give me a hand at this program.

    Whe usually don't create an entire program, ecspecially if it's
    homework, So if you could plz post some of the code you already
    programmed, You should be able to construct at least the base.

    As per above, I usually don't do people's homework for them. However, I'm feeling generous today, so you're in luck! I'll get you started. You fill in the blanks:
    Code:
    blanks
    
    int main ( void )
    {
        blanks
    
        return 0;
    }
    Now that I've done the hard part, all you have to do is fill in two little blanks, and you're done!

    No, you're not wasting your time, you're in the correct way.
    Now, did you understand what they want from you?
    determine if a store customer has exceeded the credit limit on his charge account

    This is not so hard, first of all think in your head, how could you solve this, without programming, after this, try programming, and it will be easier for you.

    If you understand well, how if's works, you can do it easilly.

    It says to input each of these facts, calculate the new balance (=beginning balance + charges -credits) determine if the new balance exceeds the customer's credit limit. For those customer's whose credit limit is exceeded, the program should display the customer's account number, credit limit, new balance ane the message Credit limit exceeded.
    I am so confused book does not give any examples and teacher didn't give any notes for it either lol. I just need some help here plz.

    Ok, you learned to input data, you have 2 types of variables:
    Ineteger and Float, to input integer use:

    Code:
    scanf("%d",&varName);
    And for input float, use:
    Code:
    scanf("%f",&varName);
    Not input all that you need to input, paste your code here, and we'll go to the next level

    This is as far as I have gotten

    #include<stdio.h>

    int main()
    {
    int account_number,total_items;
    float balance, total_credits, allowed_credits;


    printf ("Enter in account number\n");
    scanf ("%d", &account_number);
    printf ("account number is%d\n");

    return 0;

    }

    Let me save you the trouble of typing a reply after every line of code you write.
    Code:
    while not done
        prompt for account number
            look up account number
            if not found, create new account
                probably prompt for credit limit
                possibly prompt for initial balance
        prompt for action
            -- check balance
            -- pay towards bill
            -- charge something
    See the above? We call that pseudo-code. Pseudo-code is a method of outlining what you want the program to do. Break each step down into smaller steps.

    >>This is as far as I have gotten
    And your next step is to learn code tags

    >>printf ("account number is%d\n");
    Should be
    >>printf ("account number is %d\n", account_number);
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    I wrote this program but it doesnt compile any help
    Code:
    include<stdio.h>
    int main()
    {
        int acc1;
        float bal, chrg, cred, limit;
        
        printf ("Enter account number (-1 to end);\n");
        scanf ("%d", &acct1);
        
        while (acct != -1){
            printf ("enter begining balance:\n");
            scanff ("%f", &bal);
            printf ("enter total charges:\n")l;
            scanf ("%f", &chrg);
            printf ("Enter total credits!\n");
            scanf ("%f", &cred);
            printf ("Enter total credit limit:\n");
            scanf ("%f", &limit);
            
            bal=(bal+chrg)-cred;
            if (bal>limit);{
            
            printf ("account:%d", acct);
            printf ("credit limit: %.2f\n",limit);
            printf ("balance limit exceded\n");
            }
          
          }
            return 0;
            }

    *change include<stdio.h>

    into #include <stdio.h>

    u wrote somewhere scanff its scanf (one f)

    <<printf ("enter total charges:\n")l;
    drop the l ==>
    printf ("enter total charges:\n");

    u declare int acc1; but u use acct1 :s change that acct1 into acc1;
    <<if (bal>limit);{
    drop the ; ==>if (bal>limit){
    Code:
    #include <stdio.h>
    int main()
    {
    	 int acct;
    	 float bal, chrg, cred, limit;
    
        printf ("Enter account number (-1 to end)\n");
    	 scanf ("%d", &acct);
    
        while (acct != -1){
            printf ("enter begining balance:\n");
    		  scanf ("%f", &bal);
    		  printf ("enter total charges:\n");
    		  scanf ("%f", &chrg);
    		  printf ("Enter total credits!\n");
            scanf ("%f", &cred);
    		  printf ("Enter total credit limit:\n");
    		  scanf ("%f", &limit);
            
    		  bal=(bal+chrg)-cred;
    		  if (bal>limit){
    
    		  printf ("account:%d", acct);
    		  printf ("credit limit: %.2f\n",limit);
    		  printf ("balance limit exceded\n");
    		  }
    
    		}
    		  return 0;
    		  }
    the corrections i made where just corrections that were indicated by the compiler try to look urself at compiler warnings and errors this way u will solve lots of typos and other things
    ::edit::
    also try to use some indentations this way code is easier to read (im looking at the if statement right now)

    Alright. I'm fairly new to C programming myself, so maybe it's a good idea to disregard any and all of my advice. Still...

    printf ("Enter account number (-1 to end);\n");

    I don't think that the semicolon after the (-1 to end) is possible. That's an error, I think. Also, if this is an exact copy from your C source...

    scanff ("%f", &bal);

    That scanf has one two many F's in it.

    Maybe I'm wrong, but that's what I see.

    thats not an error it will just print ';' to the screen without any thing else (because the ';' sign is within the "blabla" of the printf)
