Pattern 20 : Hollow Mirrored right angle triangle pattern program in C using loops
C program to print the following Hollow mirrored triangle star pattern :
Write a C Program to print Hollow mirrored triangle pattern program. The program going to take the number of rows as the input and print the pattern with that many rows. We will use the two for loops to print the program.
Here is the example input and output pattern
Enter Number : 5

Few browsers are not showing patterns properly. So here is one screenshot of actual hollow mirrored right triangle.

#include<stdio.h> int main() { int i,j,n; // Take input from the user printf("Enter how many rows you want: "); scanf("%d",&n); // Outer for loop for rows for(i=1;i<=n;i++) { // To createt the preceding spaces before triangle for(j=1;j<=(n-i);j++) printf(" "); // two spaces // Now print the Triangle pattern for(j=1;j<=i;j++) { // We only need stars at the boarder. Hollow Triangle. if( j==i || j==1|| i==n) printf(" *"); else printf(" "); } printf("\n"); } return 0; } |
