将两个数组内容进行交换（数组一样大）

#include<stdio.h>
int main()
{
    
    
 int arr1[4]={
    
    1,2,3,4};
 int arr2[4]={
    
    5,6,7,8};
 int i = 0;
 for(;i<4;i++){
    
    
  int temp;
  temp = arr1[i];
  arr1[i] = arr2[i];
  arr2[i] = temp;
 }
   for(i=0;i<4;i++){
    
    
    printf("%d ",arr1[i]);
   }
   printf("\n");
   for(i=0;i<4;i++){
    
    
   printf("%d ",arr2[i]);
   }  
  return 0;
}
