In this article, I will show you, How to write a C program to print the mirrored right triangle star pattern. How to print hollow right triangle star pattern series with trailing spaces of n rows using for loop in C programming. Here, one thing is important to know that the rows of the right triangle.
Logic to write C program to print mirrored right triangle star pattern:
It is very easy to print mirrored right triangle star pattern in C, below I have mentioned a few steps to print the 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 trailing space.
- The outer loop iterate row times and a print newline after completing the inner loop.
- If you will look at the design carefully, then find that the first row contains row-1 space and second-row contain row-2 space so on. So to print space for loop iterate x to row times.’
- To print the star the second for loop iterate 1 to x times.
See the, C program to print mirrored right triangle star pattern:
#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=x; y<rows; ++y) { printf(" "); } // Print star for(y=1; y<=x; ++y) { printf("*"); } // Print new line printf("\n"); } return 0; }
Output:
Code Analysis:
It asks the user to enter the row number.
printf("Enter the number of rows = "); scanf("%u",&rows);
first, inner loop print space x to row-1 times.
// Print spaces for(y=x; y<rows; ++y) { printf(" "); } /
Second, for loop iterates 1 to x time to print the stars.
// Print star for(y=1; y<=x; ++y) { printf("*"); }
The outer loop print the newline after each iteration of the inner loops.
