Display mirrored and hollow mirrored parallelogram star pattern in C using while

Display mirrored and hollow mirrored parallelogram star pattern in C using while

In this article, we will discuss the concept of Display mirrored and  mirrored hollow parallelogram star pattern in C using while

In this post, we are going to learn how to write a program to print  mirrored parallelogram, and Hollow mirrored parallelogram star patterns using while loop in C programming language.

 

Print Mirrored parallelogram  star patterns Using while loop

Code to print mirrored parallelogram star pattern

Program 1

This program allows the user  to enter the number of rows ,columns and any symbols then it will display  the mirrored parallelogram    star pattern using While loop in C programming language

#include <stdio.h>
#include <stdlib.h>
int main() {
    int i,j,rows,columns;
    char ch;
    printf("Enter the number of rows\n");
    //ask input from the user
    scanf("%d",&rows); // Reading the input from user for rows
    printf("Enter the number of columns\n");
    //ask input from the user for columns
    scanf("%d%c",&columns,&ch);
    // Reading the input from user for columns
    printf("Enter the character for pattern\n");
    ch=getchar();
    // Reading the input from user as symbol
    printf("\n");//Move to next line
i=1;
    while( i<=rows){//outer while loop
            j=1;
   while( j<=i){//inner while loop
   printf(" ");//print space
    j++;
   }
   j=1;
   while(j<=columns){//inner while loop
   printf("%c",ch);//print symbol after space
    j++;
}
 printf("\n");//move to next line
 i++;
}
getch();
    return 0;
}

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

Code to print  mirrored Hollow parallelogram star pattern

Program 2

This program allows the user  to enter the number of rows ,columns and any symbols then it will display  the Hollow  mirrored parallelogram    star pattern using While loop in C programming language

#include <stdio.h>
#include <stdlib.h>
int main() {
    int i,j,rows,columns;//integer variables declaration
    char ch;//Char variable declaration
    printf("Enter the number of rows\n");
    //ask input for rows
    scanf("%d",&rows); //Reading the user input for rows
    printf("Enter the number of columns\n");
    //Ask input from the user for columns
scanf("%d%c",&columns,&ch); //Reading the user input for columns
printf("Enter the character for pattern\n");
ch=getchar();//Reading the input from the user as symbol
printf("\n");//Move to next line
i=1;
while(i<=rows){//outer for loop
        j=1;
   while(j<=i){//inner for loop
   printf(" ");//print space
 j++;
   }
   j=1;
   while(j<=columns){//inner for loop
   if(i==1 || i==rows || j==1 || j==columns){
   printf("%c",ch);//print symbol after space
   }
   else{
         printf(" ");//print space
   }
    j++;
}
 printf("\n");//move to next line
  i++;
}
getch();
    return 0;
}

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