Program to display combined Pyramid pattern in C using while loop

Program to display combined Pyramid pattern in C using while loop

In this tutorial, we will discuss the concept of a C program to display combined Pyramid pattern

In the C programming language, we can use for loop, while loop and do-while loop to display different number (binary, decimal), alphabets or star pattern programs.

In this article, we are going to learn  how to Display combined pyramid  pattern using while loop  in C language

Display combined Pyramid star pattern

Combined Pyramid star pattern 1

Program 1

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

int main()
{
    int i,j,rows;
    printf("Enter the number of rows: \n");
    scanf("%d",&rows);
    printf("\n");

    i=1;
while(i<=rows){  //parent while loop
    j=i;
  while(j<=rows){
  printf(" ");//print space
  j++;
  }
  j=1;
  while( j<=2*i-1){
  printf("*");//print star
   j++;
  }
  j=2*i;
   while(j<=2*rows-1){
  printf(" ");//print space
  j++;
   }
   j=1;
  while( j<=2*i-1){
  printf("*");//print star
  j++;
  }
  printf("\n");//move to next line
i++;
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

The C program allows the user to enter the number of rows then it displays two combined straight pyramid star pattern according to the number of rows.

Program 2

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

int main()
{
    int i,j,rows;
    printf("Enter the number of rows: \n");
    scanf("%d",&rows);
    printf("\n");

    i=1;
while( i<=rows){
    j=1;
  while(j<i){
  printf(" ");
   j++;
  }
  j=1;
  while(j<2*(rows-i+1)){
  printf("*");
   j++;
  }
  j=2;
   while(j<2*i){
  printf(" ");
  j++;
   }
   j=1;
  while( j<2*(rows-i+1)){
  printf("*");
   j++;
  }
  printf("\n");
   i++;

}
getch();
    return 0;
}

When the above code is executed, it produces the following results

The C program allows the user to enter the number of rows then it displays two combined upside-down pyramid star pattern according to the number of rows.
