In this article, I will show you, How to write a C program to print reversed mirrored right triangle star pattern. How to print reversed mirrored right triangle star pattern of n rows using for loop in C programming. Here, one thing is important to know that the rows of the triangle.
Logic to write C program to print reversed mirrored right triangle star pattern:
It is very easy to print reversed mirrored right triangle star pattern in C, below I have mentioned a few steps to print reversed mirrored triangle pattern in C:
- Enter the row value for the right triangle.
- Here I have used three loops one is the outer loop to change the line and two inner loops to print star and space.
- The outer loop iterate row times and print a newline after completing the inner loop.
- If you will look at the design carefully, then each row contains (N-x +1) star with some trailing space(where N is the row number and x is the current row number). Each row contains (x-1) space.
- So to print the space inner loop iterate 1 to x times and to print the star second inner loop iterate x to row times.
#include <stdio.h> int main() { int x = 0,y = 0; unsigned int rows = 0; printf("Enter the number of rows = "); scanf("%u",&rows); for(x=1; x<=rows; ++x) { // Print spaces for(y=1; y<x; ++y) { printf(" "); } // Print star for(y=x; y<=rows; ++y) { printf("*"); } // Print new line printf("\n"); } return 0; }
Output:
Code Analysis:
It asks the user to enter the row for the triangle
printf("Enter the number of rows = "); scanf("%u",&rows);
Each row contains (x-1) space. So to print the space inner loop iterate 1 to x times.
// Print spaces for(y=1; y<x; ++y) { printf(" "); }
Each row contains (N-x +1) star. So to print the star second inner loop iterate x to row times.
// Print star for(y=x; y<=rows; ++y) { printf("*"); }
The outer loop print the newline after each iteration of the inner loops.
