C Program to Print Inverted Right Triangle Number Pattern

In this tutorial, we will learn to create a C program that will print the Inverted Right Triangle Number Pattern in C programming

Prerequisites

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

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
While loop in C programming.

Conditional Statements in C programming.

What is an Inverted Right Angled Triangle?

This right-angle triangle is a flip triangle created using a reverse while loop. It has a base on the top side, and it is 90 Degree triangle following the Pythagoras theorem.

What is a pattern?

The patterns can be any shape or design drawn on the screen i.e. triangle, rectangle, pyramid, any other shape. In the C programming language, the patterns are generated using loops and iterative statements.

Algorithm:-

1. Declaring the required variables for the program.

2. Taking the input rows of the right-angled from the user.

3. Generating the pattern using the nested while loop.

4. Printing the right-angled triangle pattern.

5. End the program.

1. Declaring the required variables for the program.

2. Taking the input rows of the right-angled from the user.

3. Generating the pattern using the nested while loop.

4. Printing the right-angled triangle pattern.

5. End the program.

Program description that will print the Inverted Right Triangle Number Pattern:-

In today’s tutorial, we will create a program, that will print the Inverted Right Triangle Number Pattern using a while loop. First, take the input number of rows in the triangle by the user. Then we will print the right angle triangle of Numbers using the for-loop. The below is an example to print an Inverted Right Triangle Number Pattern.

Program Code:-

/*
** C program to print the Inverted Right Triangle Number Pattern **
*/
#include <stdio.h>
int main() 
{
    //declaring the required variables for the program
  	int rw, i, j;
  	//i = it will hold the integer value to control the loop. 
  	//j = it will hold the integer value to control the loop. 
  	//rw = it will hold the integer value for number of rows.
	//taking the input number of rows from the user
  	printf("Please Enter the Number of Rows:  ");
  	scanf("%d", &rw);
  //Generating the inverted right angled triangle
  	i = rw;
	
  	while ( i >= 1) 
  	{
  		j = 1 ;
      	while (  j <= i ) 
      	{
      	    //printing the right-angled triangle in inverted format
          	printf("%d", i);
          	j++;
      	}
      	i--;
      	printf("\n");
  	}
  	return 0;
}

** C program to print the Inverted Right Triangle Number Pattern **

#include <stdio.h>

int main()

{

//declaring the required variables for the program

int rw, i, j;

//i = it will hold the integer value to control the loop.

//j = it will hold the integer value to control the loop.

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

//taking the input number of rows from the user

printf("Please Enter the Number of Rows: ");

scanf("%d", &rw);

//Generating the inverted right angled triangle

i = rw;

while ( i >= 1)

{

j = 1 ;

while ( j <= i )

{

//printing the right-angled triangle in inverted format

printf("%d", i);

j++;

}

i--;

printf("\n");

}

return 0;

}

Output:-

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

rw = it will hold the integer value.

j = it will hold the integer value.
i = it will hold the integer value.

Input the number of rows for the pattern.

Code to make the pattern on the screen.
