Question

Fill in the code only using pointer variables

#include

using namespace

std; int main() {

int longside; // holds longside (length)

int wideside; // holds wideside(width)

int total; // holds total (area)

int *longsidePointer = nullpointer; // int pointer which will be set to point to length

int *widthPointer = nullpointer; // int pointer which will be set to point to width

cout << "Please input the longside of the rectangle" << endl;

cin >> longside;

cout << "Please input the wideside of the rectangle" << endl;

cin >> wideside;

// Fill in code to make longsidePointer point to longside(length) (hold its address)

// Fill in code to make widesidePointer point to wideside(width) (hold its address)

total = // Fill in code to find the total(area) by using only the pointer variables

cout << "The total is " << total << endl;

if (// Fill in the condition longside(length) > wideside(width) by using only the pointer variables)

cout << "The longside is greater than the wideside" << endl;

else if (// Fill in the condition of wideside(width) > longside(length) by using only the pointer variables)

cout << "The wideside is greater than the longside" << endl;

else

cout << "The wideside and longside are the same" << endl;

return 0;

}

}

Solution

#include <iostream>

using namespace std;

int main()
{
int longside; 

int wideside; 

int total; 

int *longsidePointer = NULL; 

int *widthPointer = NULL; 

cout << "Please input the longside of the rectangle" << endl;

cin >> longside;

cout << "Please input the wideside of the rectangle" << endl;

cin >> wideside;

// Fill in code to make longsidePointer point to longside(length) (hold its address)
    longsidePointer=&longside;
    widthPointer=&wideside;
    


total = *longsidePointer * *widthPointer ; 

cout << "The total is " << total << endl;

if (longsidePointer > widthPointer)

cout << "The longside is greater than the wideside" << endl;

else if (longsidePointer < widthPointer)

cout << "The wideside is greater than the longside" << endl;

else

cout << "The wideside and longside are the same" << endl;

return 0;
