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;
}
