C++ Program to Print Number Pattern

In this tutorial you will learn about the C++ Program to Print Number Pattern and its application with practical example.

In this tutorial, we will learn to create a C++ program that will Print Number patterns using C++ programming.

C++ Program to Print Number Pattern

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C++ programming topics:

Operators in C++ Programming.

Basic Input and Output function in C++ Programming.
Basic C++ programming.
Basic arithmetic operations.

For loop in C++ Programming.

Print Number Pattern:-

The C++ language is a very powerful programming language. In C++ programming we can perform many operations with the help of codings. The C++ language is very easy to create any pattern. In this program, we will learn to Print Number Patterns with the help below code.

Algorithm:-

STEP 1: START

STEP 2: first declare the variables

STEP 3: Take input from number of rows from the user.

STEP 4: then start the parent for loop

STEP 5: now make the child for loop

STEP 6: in this child loop print the blank spaces

STEP 7: now use another child loop to start drawing<strong> Number Pattern</strong>

STEP 8: Now this for loop will also execute under the parent for loop

STEP 9: Print "\n" for changing the line before the increment of the main loop

STEP 10: increment of the main for loop

STEP 11: return the zero value for main function

STEP 1: START

STEP 2: first declare the variables

STEP 3: Take input from number of rows from the user.

STEP 4: then start the parent for loop

STEP 5: now make the child for loop

STEP 6: in this child loop print the blank spaces

STEP 7: now use another child loop to start drawing<strong> Number Pattern</strong>

STEP 8: Now this for loop will also execute under the parent for loop

STEP 9: Print "\n" for changing the line before the increment of the main loop

STEP 10: increment of the main for loop

STEP 11: return the zero value for main function

Program:-

To Print Number Pattern.

#include <iostream>
using namespace std;

int main()
{ 
    //declare the variables for the program
    int rw,i,j;
    //rw it will hold the integer value for the number of rows
    //i it will hold the integer value for the Parent for loop
    //i it will hold the integer value for the child for loop
    
    //taking input from the user number of rows for the pattern
    cout << "Enter number of rows: ";
    cin >> rw;
    
    //Making the pattern from the nested for loop
    for(i = 1; i <= rw; ++i)
    {
        for(j = 1; j <= i; ++j)
        {
            //printing the pattern on the output
            cout << j << " ";
        }
        cout << "\n";
    }
    return 0;
}

#include <iostream>

using namespace std;

int main()

{

//declare the variables for the program

int rw,i,j;

//rw it will hold the integer value for the number of rows

//i it will hold the integer value for the Parent for loop

//i it will hold the integer value for the child for loop

//taking input from the user number of rows for the pattern

cout << "Enter number of rows: ";

cin >> rw;

//Making the pattern from the nested for loop

for(i = 1; i <= rw; ++i)

{

for(j = 1; j <= i; ++j)

{

//printing the pattern on the output

cout << j << " ";

}

cout << "\n";

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

i = it will hold the integer value to control parent for loop.
j = it will hold the integer value to control child for loop.
rw = it will hold the integer value.

Taking the input rows from the users.

Code for the pattern of the number.

Printing the rows of patterns.
