今天学习了指针的第3个作用

#include <stdio.h>

int getRemainder(int num1, int num2, int* res);
int main()
{
	int a = 10;
	int b = 3;
	int res = 0;

	int flag = getRemainder(a, b, &res);
	if (flag == 0)
	{
		printf("余数为：%d", res);

	}


	return 0;
}
int getRemainder(int num1,int num2,int*res)
{
	*res = num1 % num2;
	if (num2 == 0)
	{
		return 1;
	}
	return 0;
}
