Display a Mirrored Rhombus pattern using do-while loop in C

In this article, we will discuss the concept of Display a Mirrored Rhombus pattern using do-while loop in C

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

Display Mirrored Rhombus star patterns Using do-while loop

Code to print mirrored rhombus star pattern

Display a Mirrored Rhombus pattern using do-while loop in C — Mirrored Rhombus pattern

Program 1

This program allows the user to enter the number of rows , and any symbols then it will display the mirrored rhombus star pattern using do-while loop in C programming language

#include <stdio.h>
#include <stdlib.h>
int main() {
    int i,j,rows;
    //Declare three integer variables
    char ch;
    //Declare a char variables
    printf("Enter the number of rows\n");
    //Ask number of rows from the user
scanf("%d%c",&rows,&ch);
//Reading the number of row entered by user
printf("Enter the Symbol for pattern\n");
//Ask input from the user as symbol
ch=getchar();
//Reading the character entered by user
printf("\n");//move to next line

i=1;
do{//outer do-while loop
        j=1;
   do{//inner do-while loop
   printf(" ");//print space
 j++;
   }while(j<=i);
   j=1;
   do{//inner do-while loop
   printf("%c",ch);//print character after space
    j++;
}while(j<=rows);
 printf("\n");//move to next line
  i++;
}while(i<=rows);
getch();
    return 0;
}

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

Code to print Hollow mirrored rhombus star pattern

Program 2

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

#include <stdio.h>
#include <stdlib.h>
int main() {
    int i,j,rows;//variable declaration for integer
    char ch; //Declare a character variable
    printf("Enter the number of rows\n");
    //Ask input from the user
scanf("%d%c",&rows,&ch);
//Reading the input value
printf("Enter the Symbol for pattern\n");
ch=getchar();
//Reading the symbol for pattern
printf("\n");
i=1;
while(i<=rows){//outer for loop
        j=1;
   while(j<=i){//inner for loop
printf(" ");//print space
 j++;
   }
   j=1;
   while(j<=rows){//inner for loop
   if(i==1 || i==rows || j==1 || j==rows){
   printf("%c",ch);//print characters 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
