Question

share your program enhance your work after submitting export to repl Due: Oct 12, 2020 05:00 pm submit : back to classroom run Instructions from your teacher: #include <iostream> Complete this program. using namespace std; When the program is complete it should ask the user to enter a rectangle's length and width, then display the rectangle's area. The program calls the following functions which need to be completed: double getLength() { // Add code here } double getWidth() { // Add code here } getLength - This function should ask the user to enter the rectangle's length, then return that value as a double. get Width - This function should ask the user to enter the rectangle's width then return that value as a double. get Area - This function should accept the rectangle's length and width as arguments and return the rectangle's area as a double. The area is calculated by multiplying the length by the width. displayData - This function should accept the area as an argument and display it in a message on screen. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 double getArea(double length, double width) { // Add code here } The function names and function headers are provided to you. You just need to fill in the bodies of the functions. void displayData(double area) { // Add code here } Do not modify the main function. Your solution should only involve adding code to the functions that are called in main(). Please use the test cases to verify your solution! int main() { double length = getLength(); double width = getWidth(); double area = getArea(length, width); displayData(area); }

Answer 1

#include<iostream>
using namespace std;

int main()
{
    int n;
    
    cout<<"> Enter a number: ";
    cin>>n;
    
    for(int i = 1;i<=n;i++){
       for(int j = 1;j<=i;j++){
          cout<<i;
      }
      cout<<endl;
   }
    return 0;
}

Answer 2

#include <iostream>

using namespace std;

double getLength() {
    double length;
    cout << "Enter length(must be positive): ";
    cin >> length;
    return length;
}

double getWidth() {
    double width;
    cout << "Enter width(must be positive): ";
    cin >> width;
    return width;
}

double getArea(double length, double width) {
    return length * width;
}

void displayData(double area) {
    cout << "Area of rectangle: " << area << endl;
}

int main() {
    double length = getLength();
    double width = getWidth();
    double area = getArea(length, width);
    displayData(area);
    return 0;
}

Enter length (must be positive): 7 Enter width(must be positive): 4 Area of rectangle: 28
