reversing a string using recursive

[zai92]

ok this is what i've written till now:

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

void revDisplay(const string& a);

int main()
{
    string a;
    cout<<"Please enter a string: ";
    getline(cin, a);
    revDisplay(a);
    return 0;
}

void revDisplay(const string& a)
{
    size_t n = a.size();
    if(n == 1)
        cout << a << endl;
    else
    {
        cout << a[n-1];
        string b = a.substr(0, n-1);
        revDisplay(b);
    }
}

This will only output something like this:
Please enter a string: Cake
ekaC

I want it to ouput something like this:
Please enter a string: Cake
eCak
ekCa
ekaC <--- stops when first letter becomes last

i'm not really sure how to do this, any help or hints would be awesome thanks!

Try using string methods to remove the last character from the string and prepend it to the beginning. If you repeat this process size-1 times, you'll have the output you want.
