Thread: End program through If statement?.

Hey guys i'm wondering how I would end a program prematurely through an if statement if an invalid number is input.

I thought something like this:

Code:

int end=0;

if((number[n]>9999999)||(number[n]<-9999999))
{
    printf("All values must be between 9999999 and -9999999");
    return end;
}

}

in place of

Code:

return end;

you can use

Code:

 exit(1);

If number is unsigned that would cause the problem. Also if you didn't read the number into number[n] properly.

Just a question...
Exactly what datatype do you think your compiler will assume 9999999 is?

And what datatypes should it fit in?

Sorry I haven't replied. I have it sorted now. Thanks for all the help .
