C++ question

[Bmxpunk86pl]

Yeah im new to C++ and i have a question. Whenever i write a program, say like a conversion program, i put in my number that will be converted, but before i even see the answer, the program shuts down. Is there anyway to make it stop from shutting down?

[engjohn]

once it gets to the end of the program it will automatically close the window it was running in.

If you put a loop in the program so that you can convert multiple tempuratures then you will not have this prob..

You can also call

system("pause");

if you include the process.h header in your program.

thanks man!!!!!!!!!1

[phungilax]

you can also execute the program through DOS, and it will not shut down

engjohn, how would i do that, here is what i did and it doesnt work because it gives me an error in my compiler saying
19 untitled1.cpp
implicit declaration of function `int system(...)'

here is the simple program i made using that

#include <iostream.h>
#include <stdio.h>
#include <process.h>
int main ()
{
int var1;
cout <<"This please put in a number:";
cin>>var1;

int var2;
cout <<"Put in another number:";
cin>>var2;

int answer;
answer = var1 * var2;
cout <<"The answer is:";
cout <<answer;

system("pause");

return 0;
}

Easiest solution is to put a getchar() or a cin statement at the end. This way, once your program is finished, it sits there and waits for you to enter a key or hit return. That's how I did just about all of my C and C++ programs.

[engjohn]

#include <iostream.h>
#include <process.h>


void pause()
{
system("pause");
}

int main ()
{
int var1, var2, answer;
cout <<"This please put in a number: ";
cin>>var1;

cout <<"Put in another number: ";
cin>>var2;

answer = var1 * var2;
cout <<"The answer is: " << answer <<endl;

pause();

return 0;
}

oh ok thanks alot

[malbolgia]

getch()

the solution in c++ is endless............you will have fun if you play with it every day

that's because system() is in stdlib.h not process.h

why learn c++? when you can learn c#

this thing is new ....soon or later c++ will be like c....

I just checked and it IS in process.h AND stdlib.h on my system,
I am using Visual Studio Enterprise Edition. <-- Probably a MS thing...

It is in stdlib.h on my linux system.

From what I have read c# has the ease of VB and SOME/most of the
power of c/c++. It does NOT have all of the power of c/c++.

C# is more of a java replacement than a C++ replacement. It' just because Sun stopped them making J++ how they wanted, so they turned the old J++ into C#

can't agree more...........do you think that c# will win over java ?

i doubt it

[ButcherUK]

I think both will gain their own group of followers, people have said all sorts of languages will be replaced, but they haven't even oldies such as COBOL, Pascal and Fortran are still around :)
