C++ Program To Remove Duplicate Characters From Given String

 What is Duplicate Characters?

Duplicate Character means repeating characters.

In these program we will remove the characters that are present more than once.

Program:

#include <iostream>
using namespace std;

int main()
{
    string s = "Scrupulously";

    for(int i = 1; i < s.length(); i++)
    {
        for(int j = 0; j < i; j++)
        {
            if(s[j] == s[i])
            {   //erase is an inbuilt function used to erase char of given index
                s.erase(i,1);
                
                i--;
            }            
        }
    }

    cout << s << endl;;

    return 0;
}
