1 Recall the following functions and operators sizeof function: returns the size of a variable (ie, the number of bytes used by a variable). Note when you cout a pointer variable or value, it will be shown in hexadecimal, as indicated by the OX prefix of the number. You can cast the pointer to long if you want the address to be displayed in decimal. Write a C++program that declares three variables and three pointers that pointing to them (as below) and add cout statements to display out the size, and address of the variables. Run your program and wrnte down your answers in the blank. int a-10; double d-3.1415; // the size of d is char c'A I the size of a is: // the size of c is:.- int * pNULL; // the size of p is: ----.----. // the value of p is: double q-NULL; // the size of q is: // the value of q is: - chart-NULL; // the size of t is: the value of t is: p-ka Ithe value of p is q-d IIthe value of q is t-c II the value of t is cout
