I ran this program in my compiler and it ran but the output-screen does not stay for me to see. what could be wrong with the program?

#include<iostream.h>
main()
{
int i=5, j=6, k=7, n=3;
cout<<i+j*k-k%n<<endl;
cout<<i/n<<endl;
system ("pause")
return 0;
}

Don't run your program from the IDE, run it from the command line.

Hello

You can use getchar(); instead of system ("pause")

The code is all wrong.

- You have one semi-colon missing after system("pause")
- You are using <iostream.h> which is deprecated.
- The main() function should have an int return type.
- You are not using any namespace before cout and endl, like std::cout.

How did you compile it in the first place?

He probably didn't compile at all, but that wouldn't explain the output screen...

Besides the DOS screen just running without compiling anything.

Maybe, he's not using an IDE?

A namespace for cout is missing.
Main is missing a type.

It probably displayed an error and then quit. You can see the exact same behavior if you go to your run box in the start menu and just type in ipconfig.exe. A box will display for a fraction of a second and then close. Same thing.
