Pass by value - a copy is made

Pass by pointer ( explicit pointer)
example:
void func(int * ptr_sent)
main()
{
int i;
int *p;
p = &i;
func(p);
}

void func(int * ptr_sent)
{
*ptr_sent = *ptr_sent + 2
// adds 2 to the value in location pointed by ptr_sent
}

answers given by yen .. there is one error ... in pass by
reference .. when calling function pass the variable not
the address....fun(i) should be called instead of fun(&i)

Pass by reference (implicit pointer)
example:
void func(int &ref_sent)
main()
{
int i;
func(i); // call by reference
}

void func(int &ref_sent)
{
ref_sent = ref_sent + 2
// adds 2 to the ref_sent
// Please note that you do not need * when using reference
// Any code manipulating reference reflects changes on i
}
