C Program to print Hollow Full pyramid star Pattern

C Program to print Hollow Full pyramid star Pattern

Example :-

#include<stdio.h>
int main()

{
int i, space, row, star=0;

printf("Enter The Number ");
scanf("%d",&row);

for(i = 0; i < row-1; i++) {
for(space = 1; space < row-i; space++) {
printf(" ");
}

for (star = 0; star <= 2*i; star++) {
if(star==0 || star==2*i)

printf("*");
else
printf(" ");
}
printf("\n");
}

for(i=0; i<2*row-1; i++){
printf("*");

}
return 0;
}

C Program to Print Hollow Full Pyramid Using Stars Pattern

Explain Program

Step :1

#include <stdio.h>

int main()

{

    int i, space, row, star = 0;

#include <stdio.h> :-  printf and scanf.

 int i, space, row, star;: Declares loop variables and input variable.

 row = number of levels of the pyramid.

 i = controls outer loop (rows).

 space = manages indentation before the stars.

 star = controls how many positions are printed per row.

Step :2

User Input

printf("Enter The Number ");

scanf("%d", &row);

User input how many rows they want for the pyramid.

 If input is 5, the pyramid 

Step :3

Hollow Pyramid

for(i = 0; i < row - 1; i++) {

    for(space = 1; space < row - i; space++) {

        printf(" ");

    }

     for(star = 0; star <= 2 * i; star++) {

        if(star == 0 || star == 2 * i)

            printf("*");

        else

            printf(" ");

    }

     printf("\n");

}

How it work:

•  Loop 1)  for (i = 0; i < row - 1; i++)

• Controls each row of the hollow pyramid .

•  Runs row - 1 times (e.g., if row = 5, this loop runs 4 times).

•  Loop 2)  for (space = 1; space < row - i; space++)

• Adds spaces to align the stars in a pyramid shape.

Step :4

for(star = 0; star <= 2*i; star++)

Handle the character in the current row.

Always print * at the start (0) and end (2*i).

 In between, print a space to make it hollow.

 Step :5

Bottom Part:

for(i = 0; i < 2 * row - 1; i++) {

    printf("*");

}

loop prints a full base of stars at the bottom.
