大一C语言，2道题，，，

#include<stdio.h>

void swap(int a,int b)
{
	printf("原a的值：%d\n", a);
	printf("原b的值：%d\n", b);
	int temp;
	temp = a;
	a = b;
	b = temp;
	printf("交换后a的值：%d\n", a);
	printf("交换后b的值：%d\n", b);
}

void sum(int a[], int b[],int n)
{
	int c[100];
	printf("两个数组对应元素和：");

	for (int i = 0; i < n; i++)
	{
		c[i] = a[i] + b[i];
		printf("%d ",c[i]);
	}
}

int main() {
	int a = 12, b = 3;
	swap(a, b);
	int arr1[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
	int arr2[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
	sum(arr1, arr2, 10);
	getchar();
	return 0;
}
