Explanation of Solution

The program has been explained in the in-lined comments:

#include <iostream> 

using namespace std; 

int main()  

{  

    //declare int pointers

    int *intArrayPtr;

    int *temp;

    //creates an array of five components of type int and

    //stores the base address of the array 

    //into the pointer intArrayPtr

    intArrayPtr = new int[5];

    //contents of the base address of the array is 

    //assigned a value of 7 i.e. intArrayPtr[0] is 7

    *intArrayPtr = 7;

    //temp is assigned the value of intArrayPtr

    //so it also points to array base address

    //i.e. intArrayPtr[0]

    temp = intArrayPtr;

    //modify the contents of the array inside for loop

    for (int i = 1; i < 5; i++)

    {

        //increment pointer to the next address

        //i.e. next element in the array

        intArrayPtr++;

        //assign the value of the current element

        //pointed to by intArrayPtr with the value

        //on RHS ...

Program in C language (Please solve part 2) Part one : Write a program that does the following: Creates int array array_1 of length 10. Creates int array array_2 of length 10. Takes int values from the user of for 10 values for array_1 and array_2, each. Creates a new int array array_3 which copies the values of array_1 and array_2, in interleaved order, into it. Prints out the contents of Prints out the contents of array_1, array_2 and array_3. Part two : Repeat Part one, but this time use arrays of char (instead of int), and stop receiving input into array_1 and array_2 when the user hits Enter / newline and insert a Null character into the array
