What is Array of pointer? Give one example.

Understanding Array of Pointer: Definition and Example

An array of pointers is an array where each element of the array holds a pointer to another object or variable. The elements of the array can be accessed by their index, and the pointer contained in each element can be used to access the object or variable it points to.

Here's an example of an array of pointers in C++, where each element of the array points to an integer variable:

#include<stdio.h>
int main() {
    int* intPtrArray[5]; // declare an array of 5 pointers to integers
    
    int a = 1;
    int b = 2;
    int c = 3;
    int d = 4;
    int e = 5;
    
    intPtrArray[0] = &a; // set the first element of the array to point to variable a
    intPtrArray[1] = &b; // set the second element of the array to point to variable b
    intPtrArray[2] = &c; // set the third element of the array to point to variable c
    intPtrArray[3] = &d; // set the fourth element of the array to point to variable d
    intPtrArray[4] = &e; // set the fifth element of the array to point to variable e
    
    for (int i = 0; i < 5; i++) {
        std::cout << *intPtrArray[i] << " "; // dereference the pointer and print the value it points to
    }
    
    return 0;
}

In this example, we declare an array of 5 pointers to integers (intPtrArray), and then set each element of the array to point to a different integer variable (a, b, c, d, and e). We then loop through the array and print out the values of the integers that the pointers point to.
