In this tutorial you will learn about the C Program to Print Hollow Inverted Star Pyramid and its application with practical example.
C Program to Print Hollow Inverted Pyramid Star Pattern
In this tutorial, we will learn to create a C program that will Print the Hollow Inverted Pyramid Star Pattern in C programming.
Prerequisites
Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:
- Operators in C Programming.
- Basic Input and Output function in C Programming.
- Basic C programming.
- For loop in C programming.
- Conditional Statements in C programming.
What is Printing Hollow Inverted Pyramid Star Pattern?
The Hollow Inverted Pyramid star pattern means creating an inverted reverse triangle like a pattern on the screen to the user. But the Hollow Inverted Pyramid pattern uses “*” to draw the pattern borders only. The hollow patterns are the same as normal patterns but they have nothing in the patterns they use to print blank spaces in the center.
What is a pattern?
The patterns can be any shape or design drawn on the screen i.e. triangle, rectangle, pyramid, any other shape. In the C programming language, the patterns are generated using loops and iterative statements.
Algorithm:-
1 2 3 4 5 6 7 8 9 |
1. Declaring the required variables for the program. 2. Taking the input number of rows for <strong>Hollow Inverted Pyramid</strong> pattern from the user. 3. Generating the pattern using the nested for loop. 4. Printing the <strong>Hollow Inverted Pyramid </strong>shaped pattern. 5. End the program. |
Program description:-
In today’s tutorial, we will create a program, that will print a hollow Inverted Pyramid Star Pattern using nested for loops. First, we will be taking the size in form of rows from the user. Then we will use nested for loops to create a pattern of hollow Inverted Pyramid. Then we will print the pattern using the print function. The hollow Inverted Pyramid will start from top to bottom.
Below is an example of Printing a hollow Inverted Pyramid Star Pattern.
Program Code:-
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 |
#include<stdio.h>//indluding the header files int main()//body of the main function { //Declaring the required variable for the program int i, j, rw; //i,j = it will hold the integer value for the loops. //rw = it will hold the integer input value for the rows. //Taking the input number of rows from the user. printf("Enter Hollow Inverted Star Pyramid rows = "); scanf("%d", &rw);//Scanning the rows from the user. printf("Hollow Inverted Star Pyramid Pattern\n"); //Generating the hollow inverted pyramid. for(i = rw; i > 0; i--) { for(j = 1; j <= rw - i; j++) { printf(" "); } if(i == 1 || i == rw) { for(j = 1; j <= i * 2 - 1; j++) { //Printing the border of the hollow inverted pyramid. printf("*"); } } else { for(j = 1; j <= i * 2 - 1; j++) { if(j == 1 || j == i * 2 - 1) { printf("*"); } else { printf(" "); } } } printf("\n"); } return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- rw = it will hold the integer value.
- j = it will hold the integer value.
- i = it will hold the integer value.
Input the number of rows for the hollow inverted pyramid.
Code to make the pattern on the screen.
Printing output hollow pyramid using the loops and the print function.
