将数组A中的内容和数组B中的内容进行交换。（数组一样大）

题目比较简单，首先给定两个数组，进行直接交换。
int main()
{
int arr1[5] = { 1, 2, 3, 4, 5 };
int arr2[5] = { 5, 4, 3, 2, 1 };
int len = sizeof(arr1) / sizeof(arr1[0]);
for (int i = 0; i < len; i++)
{
int tmp = arr1[i];
arr1[i] = arr2[i];
arr2[i] = tmp;
}
for (int i = 0; i < len; i++)
{
printf("%d ", arr1[i]);
}
printf("\n");
for (int i = 0; i < len; i++)
{
printf("%d ", arr2[i]);
}
system("pause");
return 0;
}

#include<stdio.h>
void Swap(int* arr1,int * arr2 ,int len)
{
for (int i = 0; i < len; i++)
{
int tmp = arr1[i];
arr1[i] = arr2[i];
arr2[i] = tmp;
}
}
int main()
{
int arr1[5] = { 1, 2, 3, 4, 5 };
int arr2[5] = { 5, 4, 3, 2, 1 };
int len = sizeof(arr1) / sizeof(arr1[0]);
Swap(arr1, arr2,len);
for (int i = 0; i < len; i++)
{
printf("%d ", arr1[i]);
}
printf("\n");
for (int i = 0; i < len; i++)
{
printf("%d ", arr2[i]);
}
system("pause");
return 0;
}
