尝试反转交换字符串数组中的所有字符,但是,它没有正确输出。有谁知道我是否正朝着正确的方向前进?
我的代码:
#include <string>
#include <string.h>
#include <iostream>
#include <stdio.h>
#include <cstring> // for strlen()
using namespace std;
void doSwap (char &string1, char &string2) {
char temp;
temp = string1;
string1 = string2;
string2 = temp;
}
int main() {
string testingWord = "hello";
int i;
cout << testingWord << "\n";
cout << "\tBelow is testing the swap feature:\n";
for (i = 0; i < testingWord.size() - 1; i++) {
doSwap(testingWord[i], testingWord[i+1]);
}
cout << testingWord << "\n";
}
这是我的输出:
elloh
编辑:不尝试进行XOR交换?
答案 0 :(得分:0)
试试这个:
for (i = 0; i < testingWord.size() / 2; i++) {
doSwap(testingWord[i], testingWord[testingWord.size() - i]);
}
