Under POSIX systems, the best solution seems to use: #include pause ; If the process receives a signal whose effect is to terminate it (typically by typing Ctrl+C in the terminal), then pause will not return and the process will effectively be terminated by this signal. And then any time I need it in the program I have my own pause; function, without the overhead of a system pause. This is only really an issue when writing console programs that you want to stay open or stay fixated on a certain point though. Sep 25, 2015 Learn how to program in C with Dev-C IDE.

This is for the numerous people I see constantly asking how to 'pause' the console after their code runs. The explanation for how the code works is within the snippet in comments.
Basically, the 'cin.clear();' function will clear the input stream, getting rid of any newline characters that would have made methods like using the 'cin.get();' function to pause the console not work. Then, we have the 'cin.ignore();' function. This will ignore the maximum amount of characters that can be entered into the stream (numeric_limits<streamsize>::max) be ignored, or wait for a newline character ( n ). This way, the console will be 'paused' until you enter a newline character (or the max. amount of characters for the input stream, but that would take forever and be unnecessary.)
I hope this helps all of you C++ beginners who are either learning for yourselves or just getting started in a college course.

If you're in windows (like using visual studio 2005) then just use
If you're on a Unix console, you really don't need a pause after you run your code.
The snippet above may be useful for pausing at different times other than after the code runs, to run the program in chunks for example

First of all, no.. never ever use the method Chococrack mentioned. It is for amateur programmers and a shitty habit to learn. Second.. how are you using it? Show me your code.

I'll use the one line system('PAUSE') or simple cin.get(); in smaller 'amateur' code that I test things on.
For professional projects, I tend to use my IDE of choice's built in debugging tools (like breakpoints in VS).
The function you posted works fine, as does the simple one line I posted.
Flaming another contributors post is definitely not the way to go about gaining a great reputation here.

'>The function ios::clear() does not empty a stream. If the stream is in an error state it resets the stream's error flags to return it to a usable state. You still need to empty the stream by another method such as istream::igmore().
This method appears to work. But unless I'm misreading something your understanding appears to be flawed.

Found a beautifully written post regarding how to do this by Narue:
The suggestion is
clear the input stream of junk and use

We used Unity because we have a custom back-end that has good Unity integration and has a C# scripting engine. Kazap is a game we made in an internal game jam, thought it was very fun, especially in a group, and decided to just put it out there for everyone. It was ideal as a.io game, and we didn't want to spend too much time on it because we are focused on finishing the back-end that powers it (as well as maintaining Scene Fusion).Oh my, that error!

n00bs all up in this thread.
cout + cin.get() is all you need in C++
printf() + getchar() is all you need in C
printf() + getchar() is all you need in C

#include <iostream>
This won't work at all using most compilers. I dare you to try it on VC++. Using O/S and compiler dependent solutions are problematic. These include
*
*
system('pause');
* Any Linux/Unix-only solutions: unistd.h
and termios.h
* Non-standard C function getch()
, defined only in particular compilers on one O/SThe BEST answer is the original post in this thread. Please learn and understand why. Don't just post your favorite inadequate solution as the best way. In these forums we try to teach the proper way to do things, not the hackneyed way most people are taught by less-than-adequate programmers.

There was no flame. The suggestion of
system('pause');
is shitty. Nothing against you, just that suggestion.cout + cin.get() is all you need in C++
printf() + getchar() is all you need in C

printf()
is a huge hit on resources. If all you are doing it printing a character or a string, use putchar()
