printf ("enter marks between 1 to 100") ;
printf ("\n 90") ;
}
if (num >=79)
{
printf ("distinction") ;
}
else if (num >= 60)

printf ("average") ;

Answer 1

Read about taking input methods in c then check your code.
You don't have value in num or a garbage value..

edit:
Azure sample corrected code:

#include <stdio.h>

int main ( )
{
int num;

printf ("enter marks between 1 to 100") ;
scanf("%d",&num);

if (num >=79)
{
printf ("distinction") ;
}
else if (num >= 60)
{
printf ("average") ;
}

return 0;
}
