C Program to Print Exponentially Increasing Star Pattern

How to write a C Program to Print Exponentially Increasing Star Pattern with example?. And also show you how to print Exponentially Increasing Pattern with different symbols.

C Program to Print Exponentially Increasing Star Pattern

This C program allows the user to enter the maximum number of rows he/she want to return as exponentially increasing Star Pattern. Here, we are going to print the * symbols until it reaches the user-specified rows.

/* C Program to Print Exponentially Increasing Star Pattern */
#include <stdio.h>
#include <math.h>
 
int main() 
{
  int Rows, i, j;
	
  printf("Please Enter the Number of Rows:  ");
  scanf("%d", &Rows);
	
  printf("\nPrinting Exponentially Increasing Star Pattern \n");
  for ( i = 0 ; i <= Rows; i++ ) 
  {
      for ( j = 1 ; j <= pow(2, i); j++ ) 
      {
          printf("* ");
      }
      printf("\n");
  }
  return 0;
}

Please Enter the Number of Rows:  5

C Program to return Exponentially Increasing Star Pattern

This program allows the user to enter the Symbol and number of rows he/she want to print. It means, instead of printing pre-defined stars, this C Program will enable the user to enter their own character.

#include <stdio.h>
#include <math.h>
 
int main() 
{
  int Rows, i, j;
  char Ch;
  
  printf("Please Enter any Symbol:  ");
  scanf("%c", &Ch);	  
	
  printf("Please Enter the Number of Rows:  ");
  scanf("%d", &Rows);
	
  printf("\nPrinting Exponentially Increasing Star Pattern \n");
  for ( i = 0 ; i <= Rows; i++ ) 
  {
      for ( j = 1 ; j <= pow(2, i); j++ ) 
      {
          printf("%c ", Ch);
      }
      printf("\n");
  }
  return 0;
}

Please Enter any Symbol:  $
Please Enter the Number of Rows:  4

C Program to display Exponentially Increasing Pattern using While Loop

In this C program, we just replaced the For Loop with the While Loop. I suggest you refer to While Loop article to understand the logic.

#include <stdio.h>
#include <math.h>
 
int main() 
{
  int Rows, i = 0, j;
  char Ch;
  
  printf("Please Enter any Symbol:  ");
  scanf("%c", &Ch);	  
	
  printf("Please Enter the Number of Rows:  ");
  scanf("%d", &Rows);
	
  printf("\n---- Printing Exponentially Increasing Star Pattern ---- \n");
  while ( i <= Rows) 
  {
      for ( j = 1 ; j <= pow(2, i); j++ ) 
      {
          printf("%c ", Ch);
      }
      printf("\n");
      i++; 
  }
  return 0;
}
