Question

One way of obtaining a pointer to a variable is by writing something like:

line 1: int a, *p;

line 2: p = &a;

Another way of doing this is to write something like:

line 3: int *t = new int;

This allocates a memory location to which the variable t will point.

Write a function that includes the 3 lines of code above and returns the size of the memory location occupied by variable t. First, discuss how to write the function in your group then write the function and the matching main function. The function signature is:

int size_of_variable_star_t() ;

Answer 1

int size_of_variable_star_t(){
    int a, *p;
    p = &a;
    int *t = new int;
    return sizeof(t);
}
