Maybe it is fixed from this ?

#include <stdio.h>

int sum = 0;
int num = 0;

int main()
{
    
   for (int num = 0; num < 5; sum = num++)
   {
       sum = sum + sum;
   }
    
    printf("%d\n", sum);

    return 0;
}

But better maybe he means that to fix :

#include <stdio.h>

int sum = 0;
int num = 0;

int main()
{
    
   for (int num=0; num < 5; num++)
   {
       sum += (num+2)/2;
   }
    
    printf("%d\n", sum);

    return 0;
}
