将两个数组中对应元素值的交换

swap（）函数

使用中间变量交换两个数组的值

void swap(int a[], int b[],int sa)//两个数组中对应元素值的交换
{
	int i = 0;
	int j = 0;
	int temp = 0;
	for (i = 0; i < sa; i++)
	{
		temp = a[i];
		a[i] = b[i];
		b[i] = temp;
	}
}

完整测试代码

#include<stdio.h>
void swap(int a[], int b[],int sa)//两个数组中对应元素值的交换
{
	int i = 0;
	int j = 0;
	int temp = 0;
	for (i = 0; i < sa; i++)
	{
		temp = a[i];
		a[i] = b[i];
		b[i] = temp;
	}
}
int main()
{
	int i = 0;
	int a[] = { 1,2,3,4,5,6 };
	int b[] = { 9,8,7,6,5,4 };
	int sa = sizeof(a) / sizeof(a[0]);
	int sb = sizeof(b) / sizeof(b[0]);
	printf("a数组为\n");
	for (i = 0; i < sa; i++)
		printf("%d ", a[i]);
	printf("\nb数组为\n");
	for (i = 0; i < sa; i++)
		printf("%d ", b[i]);
	swap(a, b,sa);
	printf("\na数组为\n");
	for (i = 0; i < sa; i++)
		printf("%d ", a[i]);
	printf("\nb数组为\n");
	for (i = 0; i < sa; i++)
		printf("%d ", b[i]);
	return 0;
}
