system("pause") help

[Scooter341]

I'm using DevCpp and I am hoping to find out whether there is a way I can control what is diplayed when I use

code:

system ("pause");

I was hoping to change it from "Press Any Key To Continue..."

When you use this, you're simply calling a external program. "pause" is a program on Windows which simply displays the "Press any key to continue..." message, then terminates.

You can (and should, if you wish to move beyond Windows) simply write your own equivalent by printing a string to standard output and getting some input.

Yes. System calls are an easy way to write bad code. Use getch ()

[wtd]

I believe he's using C++, so using a C function would be inappropriate where C++ can easily fill the role.

code:

char answer; std::cin >> answer;

[jamonathin]

Is that the same concept as this?

c++:

int wait; std::cin >> wait;

edit: bah neva mind

If your sticking to windows you can always use the windows system call Sleep(), it takes the number of milliseconds to sleep for; although then you'll only be delaying for a set amount of time

DO NOT USE system("PAUSE"); !
It will hinder the portability of your program. Use 'cin.get()' to pause a program. If you use system("PAUSE"),that program will only work on a windows machine. With cin.get(); you increase its portability.

oh lol i do it the cheap way ->

code:

int foo; cin >> foo; return 0;

ummm, why? Just go:

code:

cout<<"Hey Man, i'll pause now"<<endl; cin.get(); return 0;

I don't see why you'd do that. That just makes you declare a var that makes your program 32 bytes bigger.

I think that's 32 bits only 4 bytes But realy declaring an int like that is nothing; it's actually created on the stack so there is no size overhead; and only minimal performance overhead (basically only the time it takes to increment the stack pointer). Either way works; but the second is much cleaner.
