Press anykey to continue in Linux C++

Question

I am not sure if being in linux makes any different, but i have found online that this:

    cout << \"Press Enter to Continue...\";
    cin.ignore(nume         


        

Answer 1

Couldn't you just use cin.get() (get one character)?

Answer 2

Here is a snippet from my code. It works in both windows and linux.

#include <iostream>

using std::cout;
using std::cin;

// Clear and pause methods
#ifdef _WIN32
// For windows
void clearConsole() {
    system("cls");
}

void waitForAnyKey() {
    system("pause");
}
#elif __linux__
// For linux
void clearConsole() {
    system("clear");
}

void waitForAnyKey() {
    cout << "Press any key to continue...";
    system("read -s -N 1"); // Continues when pressed a key like windows
}

#endif

int main() {
    cout << "Hello World!\n";
    waitForAnyKey();
    clearConsole();
    return 0;
}

In *nix, terminals usually wait for a whole line of input before sending anything to the program. Which is why the example code you posted said "Press Enter to Continue...";, and then discarded everything until the next newline.

To avoid that, you should put your terminal in non-canonical mode, which can be done using the POSIX termios(3) functions, as explained in How to check if a key was pressed in Linux?.
