C++字符串反转

方法一

#include<string.h>
#include<iostream>
using namespace std;
int main(){char s[]="abcdefghijkl";int i=0,j=strlen(s)-1;while(i<j){s[i]^=s[j]^=s[i]^=s[j];i++;j--;}cout<<s;return 0;
}

方法二

#include<string.h>
#include<iostream>
using namespace std;
int main(){char s[]="abcdefghijkl";int x=strlen(s);char res[x];for(int i=x-1;i>=0;i--){res[x-i]=s[i];}cout<<res;return 0;
}
