 Posted: Tue Sep 23, 2008 8:15 pm Post subject: [C++] How to make it freeze on cmd window? |
 |
|
I've apparently did try messing with variables, it compiled successfully, but i need it to "pause" on the cmd window.
Source:
| Code: | // operating with variables
#include <iostream>
using namespace std;
int main ()
{
// declaring variables:
int a, b;
int result;
// process:
a = 5;
b = 2;
a = a + 1;
result = a - b;
// print out the result:
cout << result;
// terminate the program:
return 0;
} |
I was messing with the variables, i'm just starting, but how do you make it like freeze on saying "4"?
I double clicked and compiled the .exe, but it just shows me a cmd window for quite a little while.
My dad wants me to learn C++ by next year, so i really need you guys's help.
Exe attached, even if you don't need it, lol.

Agreed. Use this. No doubt, other people will come in this thread telling you to use system("PAUSE") and such, but the code slovach method uses the least amount of resources (and doesnt add extra lines saying "Press any key to continue...)

Thank you!!!
And i won't make the common mistake of not putting ";" at the end of lines  .

I use getchar(), one line less trying I don't care if it takes more resource or what ever.

I asked this same question, and got something complicated no one would explain. Explain this so I know what the hell it's doing to keep it open?
Also, waxxup, you didn't need to declare "results"- in the cout you can just do "cout a+b;" or so. (wrong I know.)

sync basically discards unread characters from the input buffer.
ignore ignores a part of input.

because it needs to be executed before the program can continue. look at my other post, and there is your answer.

Doesnt that require an extra #include though?

Are you mad!?
We ALL know that this is a lot more efficient and is used in professional programs.
