Question about making spaces when present

[crowandrabbit]

Hi, I have a question about making spaces in message_a.

For example if I enter 'hi my name is' for message, then message_a will print out -------------, however I want there to be spaces when present in the message so ideally it would look something like:

hi my name is
-- -- ---- --

Could anybody point me in the right direction on how to do this?

#include <iostream>
#include <string>

using namespace std;

int main()
{
  string message;
  
  cout << "What is your message? ";
  getline (cin, message);
  message.size();
  
  string message_a(message.size(), '-');
  
  cout << "message is: " << message << endl;
  cout << "message_a is: " << message_a << endl;

}

I want there to be spaces when present in the message

when what is present in the message?

[crowandrabbit]

when spaces are present, like they are there in the message.

for example:
'hi my name is'

has 3 spaces present, one between 'hi' and 'my', another between 'my' and 'name' and another one between 'name' and 'is'

#include <iostream>
#include <string>

int main()
{
    std::string myString{};
    std::cout << "Enter your string \n";
    getline(std::cin, myString);
    for (auto& elem : myString)
    {
        if(elem != ' ')
        {
            elem = '_';
        }
    }
    std::cout << myString << '\n';
}

Ah thanks man, that worked perfectly for what I needed once I tweaked it a little for my code.
