Java Program to Print Full Pyramid of Number Pattern

Print Full Pyramid of Number Pattern

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

In this article we are going to see how to print full pyramid number pattern.

Example-1

When rows value = 5

          1
       2 3 2
     3 4 5 4 3
  4 5 6 7 6 5 4
5 6 7 8 9 8 7 6 5

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

Don’t miss the chance of Java programs examples with output pdf free download as it is very essential for all beginners to experienced programmers for cracking the interviews.

Approach:

  • Enter total number of rows and store it in an integer variable rows.
  • Take one outer for loop to iterate the rows.
  • Take two inner loops, one for loop to print the space and another while loop to print number.
  • After each iteration print a new line.

Java Code to Print Full Pyramid of Number Pattern

import java.util.Scanner;
class Main
{
public static void main(String[] args)
{
    //Create a new Scanner object
    Scanner scan = new Scanner(System.in);

    //Taking total number of rows as input from user
    System.out.print("Rows : ");
    int rows= scan.nextInt();

   //Row and column are the iterators, temp1 and temp2 are holders that hold
   //valuye after each iteration
    int numberOfRows, numberOfColumns, temp1=0, temp2=0;

   //Outer loop to iterate the rows
   //Iterates from 1 to the number of rows entered by the user
    for (numberOfRows = 1; numberOfRows <= rows; ++numberOfRows)
    {
    //Inner loop to print space
    for (numberOfColumns = 1; numberOfColumns <= rows-numberOfRows; ++numberOfColumns)
    {
        System.out.print("  ");
        ++temp1;
    }
    numberOfColumns = 0;
    //Inner loop to print number
    while(numberOfColumns!=2*numberOfRows-1)
    {
        if(temp1<=rows-1)
        {
            System.out.print((numberOfRows+numberOfColumns)+" ");
            ++temp1;
        }
        else
        {
            ++temp2;
            System.out.print((numberOfRows+numberOfColumns-2*temp2)+" ");
        }
        ++numberOfColumns;
    }
    //Resets the variables to 0 after each iteration
    temp2 = temp1 = numberOfColumns = 0;
    //Prints a newline
    System.out.println();
    }
}
}

Output:

Rows : 7

                  1
               2 3 2
            3 4 5 4 3
         4 5 6 7 6 5 4
      5 6 7 8 9 8 7 6 5
   6 7 8 9 10 11 10 9 8 7 6
7 8 9 10 11 12 13 12 11 10 9 8 7

C Code to Print Full Pyramid of Number Pattern

#include <stdio.h>

int main()
{
   //Taking total number of rows as input from user
   printf("Rows : ");
   int rows;
   scanf("%d", &rows);

   //Row and column are the iterators, temp1 and temp2 are holders that hold
   //valuye after each iteration
   int numberOfRows, numberOfColumns, temp1 = 0, temp2 = 0;

   //Outer loop to iterate the rows
   //Iterates from 1 to the number of rows entered by the user
   for (numberOfRows = 1; numberOfRows <= rows; ++numberOfRows)
   {
      //Inner loop to print space
      for (numberOfColumns = 1; numberOfColumns <= rows - numberOfRows; ++numberOfColumns)
      {
         printf("  ");
         ++temp1;
      }
      numberOfColumns = 0;
      //Inner loop to print number
      while (numberOfColumns != 2 * numberOfRows - 1)
      {
         if (temp1 <= rows - 1)
         {
            printf("%d ", (numberOfRows + numberOfColumns));
            ++temp1;
         }
         else
         {
            ++temp2;
            printf("%d ", (numberOfRows + numberOfColumns - 2 * temp2));
         }
         ++numberOfColumns;
      }
      //Resets the variables to 0 after each iteration
      temp2 = temp1 = numberOfColumns = 0;
      //Prints a newline
      printf("\n");
   }
   return 0;
}
Output:

Rows : 7

                 1
               2 3 2
            3 4 5 4 3
         4 5 6 7 6 5 4
