Thread: I've made simple code the plus calulation but it doesn't work.

Code:

#include <stdio.h>
void print_help(void)
{
 printf("\n\n");
 printf("\n******************************");
 printf("\n*         덧셈프로그램       *");
 printf("\n*                            *");
 printf("\n*                만든이 : YB *");
 printf("\n                             *");
 printf("\n******************************");
}
int process(int a, int b)
{
 int sub = 0;
 sub = a + b;
 return sub;
}
void print_sum(int sum)
{
 printf("\n 두 수의 합은 %d입니다.", sum);
}
int main()
{
 int num1 = 0, num2 = 0, sum;
 print_help();
 printf("\n 첫번째 수를 입력하세요 : ");
 scanf_s("%d", num1);
 printf("\n 두번째 수를 입력하세요 : ");
 scanf_s("%d", num2);
 sum = process(num1, num2);
 print_sum(sum);
 return 0;
}

I've made the plus caluation as above code but it doesn't work....

when I try the code build I got this error as below screenshot.



Can someone help me out from this error?

Thank you
