Chapter 1, Problem 3E

a)

Program Plan Intro

The content of array is been initialized with given values and “*p” is assigned to the beginning of the array, now after executing each instructions individually results are obtained given below.

Explanation of Solution

Explanantion:

In the above program , an integer array is been declared first. A pointer “p” points to array. The pointer “p” is been incremented to obtain second element of integer array. Finally,program displays contents of array and value of “p”

Therefore, the content of “intArray” will be $\boxed{}$

Explanation of Solution

b)

(*p)++;

The integer pointer “p” points to first elemenst of the array. So, “*(p)++” denotes that first element of array is been incremented first and then it is assigned to “*p”. Hence, first element of array increments as a result of this instruction.

This program shows execution of the construct and displays the result of the array and value of “p”.

Program:

//Select header files

#include <stdio.h>

#include<iostream>

using namespace std;

// Main function

int main(void)

{

  // Integer array with declaration

  int arr[] = {1,2,3};

Here, “p” denotes pointer to integer array...

Explanation of Solution

Explanantion:

In the above program an integer array is declared first. A pointer “p” points to array. The content pointed to by “p” is been incremented . Finally program displays contents of array and value of “p”.

Therefore, the content of “intArray” will be $\boxed{\{}$

Explanation of Solution

c)

*p++; (*p)++;

The integer pointer “p” points to first element of array. So, *p++ denotes second element of array. Hence, second element of array increments and the incremented value is stored in “p”.

This program shows the execution of the construct and displays result of array and value of “p”.

Program:

//Select header files

#include <stdio.h>

#include<iostream>

using namespace std;

// Main function

int main(void)

{

  // Integer array with declaration

  int arr[] = {1,2,3};

...

Explanation of Solution

Explanantion:

In the above program an integer array is declared first. A pointer “p” points to array. The pointer is incremented, so that it now points to second element of array . Now, the contents pointed to by “p” is been incremented. Finally the program displays contents of array and value of “p”

Therefore, the content of “intArray” will be $$
