The Strrev function in C + +

The Strrev function in C + +

There is a function strrev in C + +, which reverses the string implementation, but keep in mind that the Strrev function is valid only for character arrays and is not valid for string types.

See the code below, where I've implemented it myself:

#include <iostream> #include <string>using namespace std; int main () {char s[100] = "China"; cout<<s<<endl; Strrev (s); cout<<s<<endl;/* Strrev cannot use string str= "China" for string type; cout<<str<<endl; Strrev (Str.c_str ());cout<<str<<endl; */char str[100]= "China"; cout<<str<<endl; int head=0, Tail=strlen (str)-1; for (; head<tail; head++, tail--) {swap (Str[head], str[tail]);} cout<<str<<endl; return 0; }
