Newbie Help!

I'm getting an error where it says 'num' undeclared (first use in this function). I haven't used 'num' at all in the code.

Code:

Code:

---

/* The following program checks if a number is even or odd */

#include <stdio.h>
#include "genlib.h"
#include "simpio.h"

main()
{
      int num1, num2;
      printf ("Enter an integer ");
      num1 = GetInteger();
      num2 = num1;
      if (num1 < 0);
      num1 = -num1;
      else;
      num1 = num1;
      if (num2%2==0);
      printf ("The number %d is even and its absolute value is %d.", num2, num1);
      else
      printf ("The number %d is odd and its absolute value is %d.", num2, num1);
      getchar();
      }

Errors:

Code:

C:\Dev-Cpp\exercises\positive.c In function `main':
15 C:\Dev-Cpp\exercises\positive.c syntax error before "else"
17 C:\Dev-Cpp\exercises\positive.c `num' undeclared (first use in this function)

6 lines from the bottom you use "if (num%2==0)

i fixed that, but the error is before that.

you are closing your else statement with ; ..... you don't want to do that. Also, if statements don't get ; on their line either.

Thanks! It's my first time working with if/else statements.
