反转一个字符串

#include <iostream>using namespace std;void swap(char *c1,char *c2){char temp = *c1;*c1 = *c2;*c2 = temp;}void reverseString(char* str,int len){for(int i=0;i<=len/2;i++) {swap(&str[i],&str[len-i-1]);}}int main(){char str[] = "abcdefghijk";reverseString(str,strlen(str));cout<<str;return 0;}
