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.
