C Program to Print Inverted Pyramid Star Pattern

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 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.

What is Printing Inverted Pyramid Star Pattern?

The Inverted Pyramid star pattern means creating an inverted reverse triangle like a pattern on the screen to the user. The Inverted Pyramid pattern uses “*” to draw the pattern.

Algorithm:-

1. Declaring the required variables for the program.

2. Taking the input number of rows for plus pattern from the user.

3. Generating the pattern using the nested for loop.

4. Printing the plus shaped pattern.

5. End the program.

1. Declaring the required variables for the program.

5. End the program.

Program description:-

In today’s tutorial, we will create a program, that will print an 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 Inverted Pyramid. Then we will print the pattern using the print function. The Inverted Pyramid will start from top to bottom.

Below is an example of Print Inverted Pyramid Star Pattern.

Program Code:-

#include <stdio.h>
int main() 
{
   //declaring the variables for the program.
   int rw, i, j, spc;
   //rw = it will hold the integer value for the program.
   //Taking the input rows form the use.
   printf("Enter the number of rows: ");
   scanf("%d", &rw);//Scanning the input from the user.
   
   //Generating the pyramid
   for (i = rw; i >= 1; --i) 
   {
      for (spc = 0; spc < rw - i; ++spc)
         printf("  ");
      for (j = i; j <= 2 * i - 1; ++j)
         printf("* ");//Printing the pyramid
      for (j = 0; j < i - 1; ++j)
         printf("* ");
      printf("\n");
   }
   return 0;
}

#include <stdio.h>

int main()

{

//declaring the variables for the program.

int rw, i, j, spc;

//rw = it will hold the integer value for the program.

//Taking the input rows form the use.

printf("Enter the number of rows: ");

scanf("%d", &rw);//Scanning the input from the user.

//Generating the pyramid

for (i = rw; i >= 1; --i)

{

for (spc = 0; spc < rw - i; ++spc)

printf(" ");

for (j = i; j <= 2 * i - 1; ++j)

printf("* ");//Printing the pyramid

for (j = 0; j < i - 1; ++j)

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.
spc = it will hold the integer value.

Input the number of rows for the inverted pyramid.

Code to make the pattern on the screen.

Printing output pyramid using the loops and the print function.
