Pointer in C++: A pointer is a variable whose value will be another variable’s address. Generally, a pointer variable is declared as follows: type var-name; Here, type is the pointer’s base type and var-name is the pointer variable name. The asterisk is used to designate a variable as a pointer. Given Program: //Include libraries #include <iostream> //Use namespace using namespace std; //Define main method int main() { // Declare array int a[10]; // Declare variable int p = a; // Declare variable int i; //Loop executes until the value of i exceeds 10 for (i = 0; i < 10; i++) //Assign value i to a[i] a[i] = i; //Loop executes until the value of i exceeds 10 for (i = 0; i < 10; i++) //Display value cout << p[i] << " "; cout << endl; //Pause console window system("pause"); //Return 0 value return 0; }

Program Plan Intro

Pointer in C++:

A pointer is a variable whose value will be another variable’s address. Generally, a pointer variable is declared as follows:

type var-name;

Here, type is the pointer’s base type and var-name is the pointer variable name. The asterisk is used to designate a variable as a pointer.

Given Program:

//Include libraries

#include <iostream>

//Use namespace

using namespace std;

//Define main method

int main()

{

// Declare array

int a[10];

// Declare variable

int p = a;

// Declare variable

int i;

//Loop executes until the value of i exceeds 10

for (i = 0; i < 10; i++)

//Assign value i to a[i]

a[i] = i;

//Loop executes until the value of i exceeds 10

for (i = 0; i < 10; i++)

//Display value

cout << p[i] << " ";

cout << endl;

//Pause console window

system("pause");

//Return 0 value

return 0;

}

Students have asked these similar questions

int p =5 , q =6; void foo ( int b , int c ) { b = 2 * c ; p = p + c ; c = 1 + p ; q = q * 2; print ( b + c ); } main () { foo (p , q ); print p , q ; } Explain and print the output of the above code when the parameters to the foo function are passed by value. Explain and print the output of the above code when the parameters to the foo function are passed by reference. Explain and print the output of the above code when the parameters to the foo function are passed by value result. Explain and print the output of the above code when the parameters to the foo function are passed by name.

In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. 1. Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. 2. Develop a function that returns true if the elements are in decreasing order and false otherwise. 3. A "peak" is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. 4. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8, 1, 4, 6}, the function…

#include using namespace std; const int y = 1; int main () { int static y = 2; int i = 3, j = 4, m = 5, n = 6; %3D int a = [] (int x, int i = 1) { return x * i; } (y, 3) ; %3D int b = [=] (int x) { return [=] (int b) { return b + j; } (x) % 7; } (a); int c = [=] (int x) mutable ->int { m = 6; return [6] (int j) mutable { y = a * b; return y / j; } (x) -m; } (b) ; cout << a << endl; cout << b << endl; cout << c << endl; cout << m << endl; cout << y < endl; return 0; This program outputs 5 lines.
