Concept of Pointer Parameter

Pointers are the special variable that stores the variable address, instead of storing the variable value. Pointer is a powerful feature of a programming language. A pointer is mostly used to save memory space and improve execution time.

Question

What does the following code output?
tinclude <iostream>
void pointerUpd (double* upt);
int main() {
double* pp;
double b[6] = { 1.01, 2.02, 3.03, 4.04, 5.05 };
PP = 6 (b[4]);
double *dp = pp;
dp++;
std::cout <« *dp < std::endl;
std::cout « *pPp « std::endl;
pointerUpd (pp) ;
std::cout « *dp « std::endl;
std::cout <« *pp << std::endl;
void pointerUpd (double* upt) {
* (++upt) = 6.06;
upt = new double;
*upt = 1.01;
