Why doesn't decrement work?

Question

C++ / C#

There is a structure

struct sets{
    int* value;
    int size;
};

There is a call:

...
removeValue(set,value);

Have a function

void removeValue(sets set, int value)
{
...
    set.size--;
}

As a result, the value is not decremented. I think you should specify a pointer to this value, but I can't implement it. How would you check this?

Answer 1

removeValue(&set, value);

void removeValue(sets* set, int value)
{
    ...
    set->size--;
}

Answer 2

Perhaps passing a parameter by reference will help you.
