Algorithm to print reversed mirrored right triangle star pattern using loop
If you look closely, this pattern is similar to inverted right triangle star pattern. For Rth row, we have to print R space characters before stars.
If you look closely, this pattern is similar to inverted right triangle star pattern. For Rth row, we have to print R space characters before stars.
- Take the number of rows(N) of reversed inverted right triangle as input from user using scanf function.
- Each row(R) contains N characters, R space characters followed by N-R star (*) character.
- We will use two for loops. Outer for loop will print one row in one iteration.
- One iteration of inner loop will first print R space characters followed by N-R star (*) character
Here is the matrix representation of the mirrored triangle star pattern. The row numbers are represented by i whereas column numbers are represented by j.
C program to print reversed mirrired right triangle star pattern
#include <stdio.h>
int main() {
int i, j, rows;
printf("Enter the number of rows\n");
scanf("%d", &rows);
for (i = 0; i < rows; i++) {
for (j = 0; j < rows; j++) {
if (j < i) {
printf(" ");
} else {
printf("*");
}
}
printf("\n");
}
return 0;
}
Output
Enter the number of rows
6
