Pyramid Pattern Program

We will write a C program to print pyramid pattern and we can print half pyramid, full pyramid, inverted pyramid etc. This will help to understand the basic structure of programming. In this program , we will print the pattern of half pyramid, full pyramid and inverted pyramid  by using proper syntax and algorithms.

Program for Pyramid Pattern

Working of Program :

In the program, we will require some inputs from the user to print the pyramid pattern.

Syntax for For() Loop:

for(initialization,condition,increment/decrement)
{
    // Statements
}

Problem 1

Write a program to print the half pyramid pattern using for loop.

  • Firstly, we have to enter the input.
  • Then print that half pyramid pattern.

Code

Run 
#include<stdio.h>
int main ()
{
  int i, j, rows;
  printf (" Enter a number of rows = ");
  scanf ("%d", &rows);
  printf ("\n");
  for (i = 1; i <= rows; ++i)
    {
      for (j = 1; j <= i; ++j)
	{
	  printf ("* ");
	}
      printf ("\n");
    }
  return 0;
}

Output

Enter a number of rows = 6

Program to product numbers

Program to remainder quotient

Program for remove characters string

Program to reverse number

Program for reverse sentence recursion

Note:

In the following program we will write a program to print the half pyramid pattern using for loop.

Problem 2

Write a program to print the inverted half pyramid pattern using for loop.

  • Firstly, we have to enter the input.
  • Then print that inverted half pyramid pattern.

Code

Run 
#include<stdio.h>
int main()  
    {  
        int i, j, rows;  
        printf (" Enter the number rows = ");  
        scanf("%d", &rows);   
        printf("\n");  
        for (i = rows; i > 0; i--) 
        {  
            for (j = i; j > 0; j--) 
            {  
                printf ("* "); 
            }  
            printf ("\n");   
        }  
        return 0;      
    }

Output

Enter the number rows = 7

Problem 3 

 

Write a program to print the inverted right half pyramid pattern using for loop.

  • Firstly, we have to enter the input.
  • Then print that inverted right half pyramid pattern.

Code

Run 
#include<stdio.h>  
int main()  
    {  
        int i, j, rows, k;  
        printf (" Enter the number rows = ");  
        scanf("%d", &rows);   
        printf("\n");  
        for (i = 1; i <= rows; i++)   
        {  
            for (j = 1; j <= i; j++)   
            {  
                printf(" ");   
            }  
            for (k = i; k <= rows; k++)  
            {  
                printf("*");
            }  
            printf ("\n");   
        }  
        return 0;      
    }

Output

Enter the number rows = 9

     *****
      ****
       ***
        **
         *
