What am i doing here?

Question

...
void func(int &x){
x+=1;
}

int *CheckCondition(void(*tem)(int&)){
int *a = new int;
*a = 3;
tem(*a);
...
CheckCondition(func);
...

Can you please tell me what am i passing here: tem(*a)
Is it a value to a reference?🤔

Answer 1

You end up passing the heap address that contains the 3 so it can be changed to 4.
