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）

方法和交换两个数的值没有什么区别，在外部加入循环即可。

#include<stdio.h>#include<stdlib.h>int main(){    int arr[] = {0,1,2,3,4};    int arr1[] = {5,6,7,8,9};    int n = 0;    int i=0;    printf("arr:");    for(i = 0;i<(sizeof(arr)/sizeof(arr[0]));i++)    {        printf("%d ",arr[i]);    }    printf("\narr1:");    for(i = 0;i<(sizeof(arr1)/sizeof(arr1[0]));i++)    {        printf("%d ",arr1[i]);    }    for(i = 0;i<(sizeof(arr)/sizeof(arr[0]));i++)    {        n = arr1[i];        arr1[i] = arr[i];        arr[i] = n;        /*arr[i] = arr1[i] + arr[i];//另外两种方法交换变量        arr1[i] = arr[i] - arr1[i];        arr[i] = arr[i] - arr1[i];*/        /*arr[i] = arr[i]^arr1[i];        arr1[i] = arr[i]^arr1[i];        arr[i] = arr[i]^arr1[i];*/    }    printf("\narr:");    for(i = 0;i<(sizeof(arr)/sizeof(arr[0]));i++)    {        printf("%d ",arr[i]);    }    printf("\narr1:");    for(i = 0;i<(sizeof(arr1)/sizeof(arr1[0]));i++)    {        printf("%d ",arr1[i]);    }    system("pause");    return 0;}
