reverse a cstring in C++, note that cstring is the same string that is used in C compiler

cstring

#include <iostream>
#include <cstring>
using namespace std;

int main()
{
    char str[255];
    cout<<"Write something here";
    cin.getline(str,255);
    int len=strlen(str);

    int i;
    cout<<str<<"Length"<<strlen(str)<<endl;
    for (int i = len-1; i >=0 ; i--) {
        cout<<str[i];
    }


}
