I need a Function to read a key press in C++

Question

I'm trying to create a program who check if a specific key in keyboard is pressed and return a boolean value into a while loop

something like this:

int main(int argc, char** argv){

   std::cout << "Press the spacebar to exit loop";
   while (true){
      if (IsKeyPressed("space")){
         break;
      }
   }
   return 0;
}

I use Linux if this matters.

The C++ standard alone does not have any functionality for reading input. You have to use an external library if you want to read input. Any game development library will have features for this, such as SFML.

With SFML:

#include <SFML/Window.hpp>
int main(int argc, char** argv){

   std::cout << "Press the spacebar to exit loop";
   while (true){
      if (sf::Keyboard::isKeyPressed(sf::Keyboard::Space)){
         break;
      }
   }
   return 0;
}
