C Program to Print Star Pattern

In this tutorial, we will learn to create a C program that will Create a Star pattern using C programming.

Prerequisites

Before starting with this tutorial we assume that you are 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.

Create a Star pattern:-

The C language is a very powerful programming language. In C programming we can perform many operations with the help of codings. The c language is very easy to create any pattern. In this program, we will learn to create star-like patterns with the help of some code.

Algorithm:-

STEP 1: START

STEP 2: first declare the variables

STEP 3: then start the parent for loop

STEP 4: now make the child for loop 

STEP 5: in this child loop print the blank spaces 

STEP 6: now use another child loop to start drawing the <strong>Star </strong><strong>pattern</strong>

STEP 7: Now this for loop will also execute under the parent for loop

STEP 8: Print "\n" for changing the line before the increment of the main loop

STEP 9: increment of the main for loop

STEP 10: return the zero value for main function

STEP 1: START

STEP 2: first declare the variables

STEP 3: then start the parent for loop

STEP 4: now make the child for loop

STEP 5: in this child loop print the blank spaces

STEP 6: now use another child loop to start drawing the Star pattern

STEP 7: Now this for loop will also execute under the parent for loop

STEP 8: Print "\n" for changing the line before the increment of the main loop

STEP 9: increment of the main for loop

STEP 10: return the zero value for main function

Program:-

To Create a Star pattern

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main()
{ 
    // declaring the variables for the program
    float size,i,j,q,w;
    q=tan(M_PI*0.4);
    w=tan(M_PI*0.2);
    
    //Taking the size of the star user wanted to create
    printf("Enter the size for the pattern :- \n");
    scanf("%f",&size);
    
    for(j=ceil(size*q);j>=0;j--)
    {
    
    for(i=-ceil(0.55*size*q/w-size);i<ceil(0.55*size*q/w-size);i++)
     {
        
    
        if((j<=0.55*size*q && j>=(i+size)*w && j>=(size-i)*w)||(j>=(i+size)*w && j<=(i+size)*q && j<=(size-i)*q)||(j<=(size-i)*q && j>=(size-i)*w && j<=(i+size)*q))
            {
                //printing the pattern * at the places
                printf("*");
             }
    else{
    //printing blank spaces
    printf(" ");
    
    }
    }
    //Printing Line Break
    printf("\n");
    }
    return 0;

}

#include <stdio.h>

#include <stdlib.h>

#include <math.h>

int main()

{

// declaring the variables for the program

float size,i,j,q,w;

q=tan(M_PI*0.4);

w=tan(M_PI*0.2);

//Taking the size of the star user wanted to create

printf("Enter the size for the pattern :- \n");

scanf("%f",&size);

for(j=ceil(size*q);j>=0;j--)

{

for(i=-ceil(0.55*size*q/w-size);i<ceil(0.55*size*q/w-size);i++)

{

if((j<=0.55*size*q && j>=(i+size)*w && j>=(size-i)*w)||(j>=(i+size)*w && j<=(i+size)*q && j<=(size-i)*q)||(j<=(size-i)*q && j>=(size-i)*w && j<=(i+size)*q))

{

//printing the pattern * at the places

printf("*");

}

else{

//printing blank spaces

printf(" ");

}

//Printing Line Break

printf("\n");

}

return 0;

}

Output:-

The above program we have first initialized the required variable.

i = it will hold the integer value to control parent for loop.
j = it will hold the integer value to control child for loop.

k = it will hold the integer value to control child for loop.
size = it will hold the integer value for the number of rows of pattern.
