C program to display pyramid star pattern

C program to display pyramid star pattern

In this tutorial, we will discuss the C program to display pyramid star pattern

In this topic, we will learn how to create Pyramid star pattern  using nested for loop   in C language

Star Pyramid pattern 1

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
   int rows,i,j,k,l;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    for(i=1; i<=rows;  i++){//outer for loop
            for(j=1; j<=(rows-i)*2; j++){
                printf(" ");//print space fot pyramid
            }
            for(k=i; k>=1; k--){//inner for loop
                printf(" *");  //create left half
            }
            for(l=2; l<=i; l++){
                 printf(" *");  //create right half
            }
 printf("\n");
    }
    getch();
    return 0;
}

Star Pyramid pattern 2

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,k,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    for(i=rows; i>=1; i--){//parent for loop to rows
        for(j=i; j<=rows; j++){
        printf(" ");//print space
          }
        for(j=1; j<=(2*i-1); j++){//inner for loop
        printf("*");//print star
          }
    printf("\n");//move to next line
    }
    getch();
    return 0;
}

Inverted star pyramid pattern

Star Pyramid pattern 3

Program 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,k,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    for(i=1; i<=rows; i++){//parent for loop to rows
        for(j=1; j<=i; j++){
        printf("*");// //print star to top half
          }
           printf("\n");//move to next line
    }
        for(i=rows; i>=1; i--){//outer for loop
           for(j=1; j<=i; j++){//inner for loop
             printf("*");//print star to bottom half
          }

    printf("\n");//move to next line
        }
        getch();
    return 0;
    }

    int i,j,k,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    for(i=1; i<=rows; i++){//for loop to rows
        for(j=i; j<rows; j++){
        printf(" ");// //print space
          }
        for(j=1; j<=i; j++){//inner for loop
             printf("*");//print star to top half
          }

    printf("\n");//move to next line
        }

        for(i=rows; i>=1; i--){//for loop to rows
        for(j=i; j<=rows; j++){
        printf(" ");// //print space

          }

    printf("\n");//move to next line

        getch();
    return 0;
