how to block the screen c++

Blocking the Screen in C++

To block the screen in C++, you can use the getchar() function to wait for user input, effectively pausing the program and "blocking" the screen until a key is pressed. Here's an example:

#include <iostream>

int main() {
    std::cout << "Press any key to continue...";
    getchar();  // Wait for user input
    return 0;
}

In this example, the program displays the message "Press any key to continue..." and then waits for the user to press a key. Once a key is pressed, the program continues execution. This effectively "blocks" the screen until the user input is received.
