Objective: To understand the use of the StringBuilder class.

Thanks for playing.

Explanation / Answer

#include <iostream>
#include <string.h>

using namespace std;

int main()
{

// initializing userStr variable of type string
string userStr = "";
int i = 0;

// Keeps continue till userStr equal to (entered by user) END
while(userStr!="END") {
cout<< "Enter word: ";

// Taking input from user
cin >> userStr;

// Check whether input string equal to END or not
if(userStr != "END") {
for(i=1; i<userStr.length(); i=i+2) {

// Incrimenting i value by 2 to access element next to current one

// Replacing i indexing value in string with *
userStr[i] = '*';
}

// Print modified string
cout << userStr<< endl;
}
}
}
