Thread: guys i really need help! else if ..

guys can you help me identify what is my error?

Code:

#include<stdio.h>

int main()
{
       
       char name[30],rcode,D,d,s,S,T,t;
       float rprice,price;
       int days;
       
       printf("------------------------------------------\n\tWELCOME TO LEGEND HOTEL\t\t\n------------------------------------------");
       printf("\nRooms : Delux(D)  Twin Sharing(T)  Single(S)\n\n");
       printf("Enter your name\t\t :");
       gets(name);
       printf("Enter Room code\t\t :");
       scanf("%c", &rcode);
       printf("Enter number of days\t :");
       scanf("%d", &days);
       printf("\n\n------------------------------------------\n\tPAYMENT RECEIPT\t\t\n------------------------------------------\n");
       
       
       
             if(rcode == D || d)
             rprice = 200.00;
             price = rprice * days;
             printf("Customer Name\t: %s\n", name);
             printf("Room Type\t: Delux\n");
             printf("Room Price\t: %.2f\n", rprice);
             printf("Number of days\t: %d\n", days);
             printf("Bill\t: RM%.2f\n", price);
             
             else
             if(rcode == T || t)
             rprice = 170.00;
             price = rprice * days;
             printf("Customer Name\t: %s\n", name);
             printf("Room Type\t: Twin Sharing\n");
             printf("Room Price\t: %.2f\n", rprice);
             printf("Number of days\t: %d\n", days);
             printf("Bill\t: RM%.2f\n", price);
             
             else
             if(rcode == S || s)
             {rprice = 120.00;
             price = rprice * days;
             printf("Customer Name\t: %s\n", name);
             printf("Room Type\t: Single\n");
             printf("Room Price\t: %.2f\n", rprice);
             printf("Number of days\t: %d\n", days);
             printf("Bill\t: RM%.2f\n", price);
             
             else
             {price = 0;
             price = rprice * days;
             printf("Customer Name\t: %s\n", name);
             printf("Room Type\t: Invalid\n");
             printf("Room Price\t: %.2f\n", rprice);
             printf("Number of days\t: %d\n", days);
             printf("Bill\t: RM%.2f\n", price);
             
       
       system("pause");
       getche();
       return 0;
       
       
       }

They keep telling "In function "main"
and syntax error before "else"

else has to go with an if. It can't go with "printf("Bill\t: RM%.2f\n", price);", because that's not an if statement. You should invest in some more curly-braces.

Only the first statement after an if clause will count as part of the if clause. You need to wrap brackets around the entire block if it's more than 1 line. Else goes outside the closing brackets.

I feel like I have seen this code either on this forum or another.. hmm~

hmmm but they only will detect the 1st if statement~ im a beginner in programming, hope you guys can help me =(

but once i compile it, the room price never change at all, it is still the delux's price...

Code:

#include<stdio.h>

int main()
{
       
       char name[30],rcode,D,d,s,S,T,t;
       float rprice,price;
       int days;
       
       printf("------------------------------------------\n\tWELCOME TO LEGEND HOTEL\t\t\n------------------------------------------");
       printf("\nRooms : Delux(D)  Twin Sharing(T)  Single(S)\n\n");
       printf("Enter your name\t\t :");
       gets(name);
       printf("Enter Room code\t\t :");
       scanf("%c", &rcode);
       printf("Enter number of days\t :");
       scanf("%d", &days);
       printf("\n\n------------------------------------------\n\tPAYMENT RECEIPT\t\t\n------------------------------------------\n");
       
       
       
             if(rcode == D || d)
             {rprice = 200.00;
             price = rprice * days;
             printf("Customer Name\t: %s\n", name);
             printf("Room Type\t: Delux\n");
             printf("Room Price\t: %.2f\n", rprice);
             printf("Number of days\t: %d\n", days);
             printf("Bill\t: RM%.2f\n", price);
             }
             else
             if(rcode == T || t)
             {rprice = 170.00;

             }

             }
             else

             printf("Bill\t: RM%.2f\n", price);
             }
       
       
       
       
       
       
       
       
       
       system("pause");
       getche();
       return 0;
       
       
       }

General style tips:

* limit your source code to 80 characters per line

* don't linear declare a bunch of variables. It's better to declare a variable as close to where it's used as possible and initialize it as soon as you can.

* don't put code on the same line as a brace, unless it's a comment " */ end of if block */ " etc.

* put a space after a closing brace
