Program to Print Asterisk Star Pattern
In this article we are going to see how to print the asterisk star pattern
Example-1 When row value=4 * * * * * * * * * *** * *** * * * * * * * * *
Example-2: When row value=10 * * * * * * * * * * * * * * * * * * * * * * * * *** * *** * * * * * * * * * * * * * * * * * * * * * * * *
Now, let’s see the actual program to print it.
Have you mastered basic programming topics of java and looking forward to mastering advanced topics in a java programming language? Go with these ultimate Advanced java programs examples with output & achieve your goal in improving java coding skills.
Approach:
- Enter length of the line and store it in an integer variable
size
. - Take outer for loop to iterate the rows.
- Take inner for loop, to print space and star.
- After each iteration print a newline.
JAVA Code:
Method-1 : Static Star Character
import java.util.Scanner; class Main { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.print("Stars : "); // Taking number of stars in a segment // as input from user int stars=scan.nextInt(),r,c; //Outer Loop for(r=1;r<2*stars;r++) { //Inner loop for(c=1;c<2*stars;c++) { if(c==stars || r==c || r+c==2*stars) System.out.print("*"); else System.out.print(" "); } //Prints a newline System.out.println( ); } } }
Output Stars : 8 * * * * * * * * * * * * * * * * * * *** * *** * * * * * * * * * * * * * * * * * *
Method-2 : User Input Character
import java.util.Scanner; class Main { public static void main(String[] args) { int r,c; Scanner scan = new Scanner(System.in); // Taking number of stars in a segment // as input from user System.out.print("Stars : "); int stars=scan.nextInt(); System.out.print("Character : "); char character=scan.next().charAt(0); //Outer Loop for(r=1;r<2*stars;r++) { //Inner loop for(c=1;c<2*stars;c++) { if(c==stars || r==c || r+c==2*stars) System.out.print(character); else System.out.print(" "); } //Prints a newline System.out.println( ); } } }
Output Stars : 8 Character : * * * * * * * * * * * * * * * * * * * *** * *** * * * * * * * * * * * * * * * * * *
C Code:
#include <stdio.h> #include <math.h> int main(int argc, char const *argv[]) { printf("Stars : "); //Taking number of stars in a segment as input from user int stars, r, c; float d; scanf("%d", &stars); //Outer loop for (r = 1; r < 2 * stars; r++) { //Inner loop for (c = 1; c < 2 * stars; c++) { if (c == stars || r == c || r + c == 2 * stars) printf("*"); else printf(" "); } printf("\n"); //Prints a newline } return 0; }
Output Stars : 8 * * * * * * * * * * * * * * * * * * *** * *** * * * * * * * * * * * * * * * * * *
C++ Code:
#include <iostream> #include <math.h> using namespace std; int main(int argc, char const *argv[]) { cout << "Stars : "; //Taking number of stars in a sefment as input from user int stars, r, c; cin >> stars; //Outer loop for (r = 1; r < 2 * stars; r++) { //Inner loop for (c = 1; c < 2 * stars; c++) { if (c == stars || r == c || r + c == 2 * stars) cout << "*"; else cout << " "; } //Prints a newline cout << endl; } return 0; }
Output Stars : 8 * * * * * * * * * * * * * * * * * * *** * *** * * * * * * * * * * * * * * * * * *
