Last Updated : 27 Nov, 2022

The task is to hide and Show the console window of a C++ program. The program for the same is given below.

Note: The results of the following program can only be seen when it is executed on a console.

Example:

C++

// C++ program to hide and show a console window 
#include <iostream> 
#include <windows.h> 
  
using namespace std; 
  
void countdown() 
{ 
    cout << "3" << endl; 
    Sleep(1000); 
    cout << "2" << endl; 
    Sleep(1000); 
    cout << "1" << endl; 
    Sleep(1000); 
    cout << "0" << endl; 
} 
  
int main() 
{ 
    countdown(); 
    HWND window; 
    AllocConsole(); 
    // You Can Find HANDLE of other windows too 
    window = FindWindowA("ConsoleWindowClass", NULL); 
    ShowWindow(window, 0); 
  
    countdown(); 
    ShowWindow(window, 1); 
}

Output:

Explanation: The above program counts from 3 to 1 before the Console Window disappears. After the window has disappeared, the ShowWindow helps the program so that the Console Window reappears again after counting from 3 to 1(executing the countdown function).

The execution of the program can be understood by understanding the key functions of the program.

#include<windows.h> – The windows.h header in C++ programming languages are specifically designed for windows and contain a very large number of windows specific functions.
AllocConsole()- AllocConsole initializes standard input, standard output, and standard error handles for the new console.
ShowWindow()- Sets the specified window’s show state.
FindWindowA()– Takes string parameters and checks whose class name and window name match the specified strings
