C Program To Print Pyramid Star Pattern

Ex: Write a C program to print  pyramid star pattern. How to write a C program to print  pyramid star pattern. C program to print  pyramid star pattern.

Input from user:

Enter the number:

7

Expected output:

       *

      **

     ***

    ****

   *****

  ******

 *******

  Step by step logic of the given program:

1. Accept input (number) from user which shows size of the pyramid, declare variable say no.

2. Run one outer for loop from 1 to no:

  for(i=1;i<=no;i++)

3. To print spaces run another for loop from i to no-1:

for(j=i;j<no;j++)

    {

    printf(" ");

    }

4. To print star run another one inner for loop from 1 to i:

for(k=1;k<=i;k++)

    {

    printf(" *");

    }

5. For new row, move to next line using \n.

Program:

#include<stdio.h>

void main()

{

  int i,j,k,no;

  printf("Enter the number:\n");

  scanf("%d",&no);

  for(i=1;i<=no;i++)

  {

  /*Print spaces*/

    for(j=i;j<no;j++)

    {

  printf(" ");

    }

    /*print star*/

    for(k=1;k<=i;k++)

    {

    printf(" *");

    }

    /*Move to the next line*/

  printf("\n");

  }

  

}

Above Program's show's the following output:
