Program in C

Here is the source code of the C Program to Print the V Star Pattern.

Code:

#include <stdio.h>
int main()
{
  printf("Enter the row size:");
  int row_size;
  scanf("%d", &row_size);
  int in, out, p;
  int print_control_x = 1;
  int print_control_y = row_size * 2 - 1;
  for (out = 1; out <= row_size; out++)
  {
    for (in = 1; in <= row_size * 2; in++)
    {
      if (in == print_control_x || in == print_control_y)
      {
        printf("*");
      }
      else
      {
        printf(" ");
      }
    }
    print_control_x++;
    print_control_y--;
    printf("\n");
  }
}

Input/Output:

Enter the row size:5

Program in Java

  

Here is the source code of the Java  Program to Print the V-shaped Star Pattern.

Code:

import java.util.Scanner;
public class StarPattern12 {
    public static void main(String[] args) {
        Scanner cs = new Scanner(System.in);
        System.out.println("Enter the row size:");
        int out, in;
        int row_size = cs.nextInt();
        int print_control_x = 1;
        int print_control_y = row_size * 2 - 1;
        for (out = 1; out <= row_size; out++) {
