command to shutdown exe

Hello.
I want to shutdown a code if some condition is met.

Code:

if(condition is true){
  some command to end the exe
}

for example,

Code:

#include <stdio.h>
#include <math.h>
int main()
int a;
scanf("%d",&a);
if(a==5){
(command to shutdown application)
}
else{
...
}
system("PAUSE");
}

Thanks.
D.

Use exit from stdlib.h .

Or just

Code:

return 0;

if you are in main().

The returned integer is a primitive way of telling the OS whether the program execution is successful. 0 means success. Anything other than 0 means failure.

What is the 'modern' way ?

There is no 'modern' way.

To do anything more sophisticated there will need to be some way to classify failures, and an OS is too general purpose to do that.

It doesn't really matter anyway, since the OS doesn't care if the program was "successful" or not. The status code from a program is generally used by other programs and scripts to decide what to do on success or failure. A small integer is enough to indicate this.

This applies to systems like Windows and *nix, at least. Systems like VMS have a more sophisticated concept of return codes, but even on those systems you return 0 or EXIT_SUCCESS from C to indicate success and EXIT_FAILURE for failure.
