The statement numptr++ increments a pointer to int.  (*numptr)++ increments the
value pointed to by numptr.

This is the function that you want:

void increment(unsigned int *numptr)
{
    (*numptr)++;
}

Subject: [OT]: Pointer problem! Please help!


Hello,

I am using MCC18 with 18F452 MCU.  I have this very simple pointer program but
it doesn't seem to work correctly.  For some reason, the variable "num" doesn't
get incremented at all.  Did I do something wrong?

void increment(unsigned int *numptr)
{
 numptr++;
}

void main (void)
{
 unsigned int num = 1;
 increment(&num);

}
