Program to Print Inverted V Star Pattern
In this article we are going to see how to print the inverted V star pattern
Example-1 When rows value = 5 * * * * * * * * *
Example-2 When rows value = 6 * * * * * * * * * * *
Now, let’s see the actual program to print it.
Enhancing programming skills is very important no matter what language you have chosen. So, practice frequently with these simple java programs examples and excel in coding the complex logic.
Approach:
- Enter the number of rows to print and store it in an integer variable
rows
. - Take first for loop to print all rows.
- Take inner for loop to print column values and one to print empty spaces.
- Then go on printing the star symbols according to the iteration.
JAVA Code:
Method-1 : Static Star Character
import java.util.Scanner; class Main { public static void main(String[] args) { int r,s=0, c, rows; Scanner scan = new Scanner(System.in); System.out.print("Enter Rows : "); //Taking total rows as input from user rows = scan.nextInt(); for(r = rows-1; r>= 0; r--) {//Outer Loop for(c = rows-1;c>s;c--) //Inner loop to print first half star System.out.print(" "); System.out.print("*"); for(c=1;c<(s*2);c++) //Inner loop to print mid gap System.out.print(" "); if(r<rows-1) //Condition to print second half star System.out.print("*"); s++;//counter //Prints a newline System.out.println(); } } }
Output Enter Rows : 9 * * * * * * * * * * * * * * * * *
Method-2 : User Input Character
import java.util.Scanner; class Main { public static void main(String[] args) { int r,s=0, c, rows; char d; Scanner scan = new Scanner(System.in); //Taking total rows as input from user System.out.print("Enter Rows : "); rows = scan.nextInt(); //Taking any random character as input from user System.out.print("Enter Character : "); d = scan.next().charAt(0); for(r = rows-1; r>= 0; r--) {//Outer Loop for(c = rows-1;c>s;c--) //Inner loop to print first half star System.out.print(" "); System.out.print(d); for(c=1;c<(s*2);c++) //Inner loop to print mid gap System.out.print(" "); if(r<rows-1) //Condition to print second half star System.out.print(d); s++;//counter //Prints a newline System.out.println(); } } }
Output Enter Rows : 9 Enter Character : v v v v v v v v v v v v v v v v v v
C Code:
#include <stdio.h> int main(int argc, char const *argv[]) { printf("Rows : "); //Taking rows as input from user int rows, s = 0, r, c; scanf("%d", &rows); for (r = rows - 1; r >= 0; r--) { //Outer Loop for (c = rows - 1; c > s; c--) //Inner loop to print first half star printf(" "); printf("*"); for (c = 1; c < (s * 2); c++) //Inner loop to print mid gap printf(" "); if (r < rows - 1) //Condition to print second half star printf("*"); s++; //counter //Prints a new line printf("\n"); } return 0; }
Output Enter Rows : 9 * * * * * * * * * * * * * * * * *
C++ Code:
#include <iostream> using namespace std; int main(int argc, char const *argv[]) { cout << "Rows : "; //Taking rows as input from user int rows, s = 0, r, c; cin >> rows; for (r = rows - 1; r >= 0; r--) { //Outer Loop for (c = rows - 1; c > s; c--) //Inner loop to print first half star cout << " "; cout << "*"; for (c = 1; c < (s * 2); c++) //Inner loop to print mid gap cout << " "; if (r < rows - 1) //Condition to print second half star cout << "*"; s++; //counter //Prints a new linee cout << endl; } return 0; }
Output Enter Rows : 9 * * * * * * * * * * * * * * * * *
