Java Program to Print Right Angled Triangle with Decreasing Number Pattern

Program to Print Right Angled Triangle with decreasing  Number Pattern

In the previous article, we have discussed Java Program to Print Right Angled Triangle with Increasing Number Pattern

In this article we will see how to print Right Angled Triangle with Decreasing Number Pattern.

Example-1

When size value=5

5
5 4
5 4 3
5 4 3 2
5 4 3 2 1
Example-2:

When size value=4

4
4 3
4 3 2
4 3 2 1

Now, let’s see the actual program to print it.

Interested in programming and want to excel in it by choosing the short ways. Then, practicing with the available Java Program list is mandatory.

Approach:

• Enter total size and number store them in integer variables size.
• Take one outer for loop to iterate the rows,
• Take one inner for loop to iterate the columns.
• After each iteration print a newline.

Java Code to Print Right Angled Triangle with Decreasing Number Pattern

import java.util.Scanner;
class Main
{
public static void main(String[] args)
{
// taking size of no. of iteration
//Row and column are the iterators
int size , numberOfRows , numberOfColumns;
// Create a new Scanner object
Scanner scanner = new Scanner(System.in);
// Get the number of rows from the user
System.out.print("Enter the number of rows : ");
size = scanner.nextInt();
//Outer loop to iterate the rows
//Iterates from size to 1
for (  numberOfRows = size; numberOfRows >=1 ; numberOfRows--)
{
//Inner loop to iterate the columns
//Iterates from size to row value
for (  numberOfColumns = size ; numberOfColumns >= numberOfRows ; numberOfColumns--)
{
//Prints the num value
System.out.print(numberOfColumns + " ");
}
// printing in new line
System.out.println();
}
}
}

Output :

Enter the number of rows : 5

5
5 4
5 4 3
5 4 3 2
5 4 3 2 1

C Code to Print Right Angled Triangle with Decreasing Number Pattern

#include <stdio.h>
#include <stdlib.h>
int main()
{
int size , numberOfRows , numberOfColumns;
printf("Enter the number of rows : ");
scanf ("%d",&size);
for (  numberOfRows = size; numberOfRows >=1 ; numberOfRows--)
{
for (  numberOfColumns = size ; numberOfColumns >= numberOfRows ; numberOfColumns--)
{
printf("%d ",numberOfColumns);
}
printf("\n");
}
return 0;
}

Output :

Enter the number of rows : 5

5
5 4
5 4 3
5 4 3 2
5 4 3 2 1

C++ Code to Print Right Angled Triangle with Decreasing Number Pattern

#include <bits/stdc++.h>
using namespace std;
int main()
{

int size , numberOfRows , numberOfColumns;
printf("Enter the number of rows : ");
scanf ("%d",&size);
for (  numberOfRows = size; numberOfRows >=1 ; numberOfRows--)
{
for (  numberOfColumns = size ; numberOfColumns >= numberOfRows ; numberOfColumns--)
{
cout << numberOfColumns;
}
cout << "\n";
}
return 0;
}


Output :

Enter the number of rows : 5

5
5 4
5 4 3
5 4 3 2
5 4 3 2 1
