Expert's answer

using namespace std;

void replace(string & str, const string & from, const string & to)
{
if(from.empty())
return;

int start_pos = 0;

while((start_pos = str.find(from, start_pos)) != str.npos)
{
str.replace(start_pos, from.length(), to);
start_pos += to.length();
}

Thank you so much.. I really appreciate it. I'm sorry for not being specific at first. Actually, I have project and the project asked to do hangman game. Firstly, I have to compare the country name with the user guessed letter. But, at the same time I have to display the underscore to represent the hidden country name. Once the user enter one of the correct country name, then how can I replace the underscore with correct letter and correct position?
