1.for循环实现字符串逆置
#include <iostream>
using namespace std;
int main() {
string str;
cout << "请输入一个字符串：" << endl;
cin >> str;
int j = str.length() - 1; //必须要放在输入字符串之后
for (int i = 0; i < j; i++) {
int tmp = str[i];
str[i] = str[j];
str[j] = tmp;
j--;
}
cout << str << endl;
system("pause");
return 0;
}
2.while循环实现字符串逆置
#include <iostream>
#include <stdio.h>
using namespace std;
int main() {
string str;
int i = 0;
char tmp;
cout << "请输入一个字符串：" << endl;
cin >> str;
int j = str.length() - 1;
while (i < j) {
tmp = str[i];
str[i] = str[j];
str[j] = tmp;
i++;
j--;
}
cout << str << endl;
system("pause");
return 0;
}
