Program to Print Flag Number Pattern

In the previous article, we have discussed  Java Program to Print Zig Zag Number Pattern

In this article we are going to see how to print the flag number pattern.

Example-1

When rows value = 5

0
11
222
3333
44444
0
1
2
3
4

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

Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

Approach:

  • Enter the number of rows to print and store it in an integer variable rows.
  • Take an outer for loop to print the triangle once.
  • Take inner for loop to print the triangle.
  • Finally take a for loop to print the pole of the flag.

Java Code to Print Flag Number Pattern

import java.util.Scanner;
class Main
{
    public static void main(String[] args)  
    {  
    
        Scanner scan = new Scanner(System.in);
        System.out.print("Rows : ");
        //Taking total rows as input from user
        int r, c, rows = scan.nextInt();
        
            //Outer loop to print the top triangle two times
            for(r = 0; r<rows;r++)
            {
                //Inner loop that prints the triangle
                for(c = 0; c<=r;c++)
                    System.out.print(r);
            //Prints a new line
            System.out.println();
            }
           
        
        for(r = 0; r<rows;r++)
            //Another loop to print the pole of the flag
            System.out.println(r);
    }
}
Output:

Rows: 5

0 
11
222
3333
44444
0
1
2
3
4

C Code to Print Flag Number Pattern

#include <stdio.h>
int main(int argc, char const *argv[])
{
    // Starting ASCII value taken 65
    int ascii=65;
    printf("Rows : ");
    //Taking rows as input from user
    int rows, r, c;
    scanf("%d", &rows);
    
        //Outer loop to print the top triangle two times
        for (r = 0; r < rows; r++)
        {
            //Inner loop that prints the triangle
            for (c = 0; c <= r; c++)
                printf("%d",r);
            //Prints a new line
            printf("\n");
        }
    
       for (r = 0; r < rows; r++)
        //Another loop to print the pole of the flag
           printf("%d \n",r);
    return 0;
}

Output: Rows: 5 0 11 222 3333 44444 0 1 2 3 4
