How To Exit Program In Dev C++
When running a program in the console you can close it with ctrl-C, but what we want to discuss here is programmatically exiting. Let's start with the most drastic one, and see why you're better off not using it. The process core module provides a handy method that allows you to programmatically exit from a Node.js program: process.exit. The C library function void exit(int status) terminates the calling process immediately. Any open file descriptors belonging to the process are closed and any children of the process are inherited by process 1, init, and the process parent is sent a SIGCHLD signal. Oct 31, 2015 In a C program, the main function often returns a value to the operating system. Usually this is accomplished by using the return keyword. However, we can also return a value by using the exit. One way to get input into a program or to display output from a program is to use standard input and standard output, respectively.All that means is that to read in data, we use cin (or a few other functions) and to write out data, we use cout. When we need to take input from a file (instead of having the user type data at the keyboard) we can use input redirection. Exit Prototype: void exit(int ExitCode); Header File: stdlib.h (C) or cstdlib (C) Explanation: Exit ends the program. The ExitCode is returned to the operating system, similar to returning a value to int main.
Hello, I am a total beginner at c++
I am writing a console program and I am wondering how I should do to exit the
program, like if the user is asked
Do you want to continue ( yes/no) and the user enters no then I want the console
to shut down..

Within main, finish the program with return 0;
std::string isShutdown;
std::cout << 'Shutdown? Y/N' << std::endl;
std::cin >> isShutdown;
if (isShutdown 'Y')
{ return 0;}
You can also end a program by using abort() and exit(), but they place additional responsibilities on the conscientious programmer. Using return is the standard way.
In the C Programming Language, the exit function calls all functions registered with atexit and terminates the program. File buffers are flushed, streams are closed, and temporary files are deleted.
