Printing Heart Pattern Program Using Star

Introduction

In this lab, we will learn how to use C++ programming language to print a Heart-Shaped Pattern program using stars. We will learn how to use Control statements to make the heart pattern according to user input.

Include Required Libraries

We will create a new file named main.cpp in the ~/project directory using the following command:

touch ~/project/main.cpp

In this step, we will include the necessary libraries in our C++ code. Open the main.cpp file in your text editor and write the following code:

#include<iostream>
using namespace std;

Define User Input Variable

In this step, we will define a variable to take input from the user. We will later use this variable to make the heart pattern. Add the following code after the previous step code:

int main()
{
    int n;
    // take user input
    cout << "Enter Heart Size (4-8): ";
    cin >> n;
    // check if input is 0
    if (n == 0) {
        return 0;
    }
    // check if input is even
    if (n % 2 != 0) {
        n++;
    }
    return 0;
}

Print Heart Pattern

In this step, we will use Control statements to make the heart pattern according to the user input. Add the following code after the previous step code:

int main()
{
    int n;
    // take user input
    cout << "Enter Heart Size (4-8): ";
    cin >> n;
    // check if input is 0
    if (n == 0) {
        return 0;
    }
    // check if input is odd
    if (n % 2 != 0) {
        n++;
    }
    // print heart pattern
    for (int row = 0; row < n; row++) {
        for (int col = 0; col < n + 1; col++) {
            if ((row == 0 && col % 3 != 0) ||
                (row == 1 && col % 3 == 0) ||
                (row - col == 2) ||
                (row + col == n + 3))
            {
                cout << "*";
            }
            else {
                cout << " ";
            }
        }
        cout << endl;
    }
    return 0;
}

Compile and Run the Code

In this step, we will compile and run the code in the Ubuntu terminal. Save the main.cpp file and open the terminal. Run the following command:

g++ main.cpp -o main && ./main

Now, enter any number between 4 and 8 in the terminal window to see the heart-shaped pattern made of stars.

Summary

In this lab, we learned how to use C++ programming language to print a Heart-Shaped Pattern program using stars. We used Control statements to make the heart pattern according to user input. We created a C++ code file in the ~/project directory, compiled and executed the code to print a heart-shaped pattern in the Ubuntu terminal.
