Re: Reverse a pointer to a set of integers

You have to do it for EACH i.
So put it in for loop

Re: Reverse a pointer to a set of integers

yes sure that's what i did and got the result 1...50...1. It's weird and i'm sure i have checked my loops a couple of times. Perhaps any other alternatives?

Re: Reverse a pointer to a set of integers

Please post entire code, because your code should work then.

Re: Reverse a pointer to a set of integers

here:

C Syntax (Toggle Plain Text)
int temp[ptr_size];
int ptr_size2 = ptr_size;
 
for (i=0;i<ptr_size;i++) {
temp[i] = ptr[ptr_size2--];
}
 
for (i=0;i<ptr_size;i++) {
ptr[i] = temp[i];
}
int temp[ptr_size];
int ptr_size2 = ptr_size;

for (i=0;i<ptr_size;i++) {
temp[i] = ptr[ptr_size2--];
}

for (i=0;i<ptr_size;i++) {
ptr[i] = temp[i];
}

The second for loop is to get back a reversed ptr.
