Program to Print Right Angled Triangle with Decreasing Character Pattern
In this program we are going to see how to print the right angled triangle with decreasing character pattern.
Example-1 When character=h & row value=3 h g f e d c
Example-2: When character=z & row value=5 Z Y X W V U T S R Q P O N M L
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 the character and store it in a variable
c
- Then enter total row and store it in an integer variable
row_count
. - Take one outer for loop to iterate the rows.
- Take one inner loop to iterate the columns and print the character.
- After each iteration print a new line.
JAVA CODE:
import java.util.Scanner; class Main { public static void main(String[] args) { Scanner scan = new Scanner(System.in); //Taking character to be printed as // input from the user System.out.print("Last Character : "); char c = scan.next().charAt(0); //Taking number of rows as input from the user System.out.print("Rows : "); int row_count = scan.nextInt(); int row, col; //Converting the character to its ascii value int asciiValue = (int) c; //Checks whether the character is a letter or not if(asciiValue>=65&&asciiValue<=122) { //Outer loop to iterate rows for(row = 0; row<row_count; row++) { //Inner loop to iterate columns for(col = 0; col<row+1; col++) { System.out.print(c+" "); //Decrementing the character c--; } //Prints a newline System.out.println(); } } } }
Output: Last Character : Z Rows : 5 Z Y X W V U T S R Q P O N M L
C CODE:
#include <stdio.h> int main() { //Taking character to be printed as input from the user printf("Last Character : "); char c; scanf("%c", &c); //Taking number of rows as input from the user printf("Rows : "); int row_count; scanf("%d", &row_count); int row, col; //Converting the character to its ascii value int asciiValue = (int)c; //Checks whether the character is a letter or not if (asciiValue >= 65 && asciiValue <= 122) { //Outer loop to iterate rows for (row = 0; row < row_count; row++) { //Inner loop to iterate columns for (col = 0; col < row + 1; col++) { printf("%c ", c); //Decrementing the character c--; } //Prints a newline printf("\n"); } } return 0; }
Output: Last Character : Z Rows : 5 Z Y X W V U T S R Q P O N M L
C++ CODE:
#include <iostream> using namespace std; int main(int argc, char const *argv[]) { //Taking character to be printed as input from the user cout << "Last Character : "; char c; cin >> c; //Taking number of rows as input from the user cout << "Rows : "; int row_count; cin >> row_count; int row, col; //Converting the character to its ascii value int asciiValue = (int)c; //Checks whether the character is a letter or not if (asciiValue >= 65 && asciiValue <= 122) { //Outer loop to iterate rows for (row = 0; row < row_count; row++) { //Inner loop to iterate columns for (col = 0; col < row + 1; col++) { cout << c << " "; //Decrementing the character c--; } //Prints a newline cout << endl; } } return 0; }
Output: Last Character : Z Rows : 5 Z Y X W V U T S R Q P O N M L
