Implementing "Press Any Key to Continue..." in C

Problem:

When attempting to write a C program that prompts users to press any key to proceed, the program doesn't behave as expected. Input handling, particularly for key detection, is proving challenging.

Solution:

To simulate the "Press any key to continue..." functionality, we leverage platform-specific system calls.

Windows (Visual Studio):

<code class="c++">#include <iostream>
#include <Windows.h>

int main() {
    std::cout << "Press any key to continue...";
    system("pause");
}</code>
Copy after login

By invoking system("pause"), we display the prompt on the console and halt execution until a key is pressed.

macOS and Linux (G /Clang ):

<code class="c++">#include <iostream>
#include <cstdio>

int main() {
    std::cout << "Press any key to continue...";
    system("read");
}</code>
Copy after login

In these platforms, system("read") fulfills the same purpose.

Explanation:

Both pause and read are system-level commands that temporarily suspend the program's execution, prompting the user to enter input. When any key is detected, the program resumes execution and the user can proceed with the next line of code.
