In this article, we will discuss the concept of C++ code:Print Mirrored Rhombus star pattern using do-while loop
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.
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 <iostream> #include <conio.h> using namespace std; int main() { int i,j,rows; //Variable declaration for integer char ch; //Variable declaration for character cout<<"Enter the number of rows\n"; //Ask input from the user for Number of rows cin>>rows; //Reading the number of rows value cout<<"Enter the Symbol for pattern\n"; //Ask input from the user for Symbol cin>>ch; //Reading the character value cout<<"\n"; //move to next line i=1; do{//outer while loop j=1; do{//inner while loop cout<<" ";//print space j++; } while(j<=i); j=1; do{//inner while loop cout<<ch;//print symbol after space j++; }while(j<=rows); cout<<"\n";//move to next line i++; }while(i<=rows); getch(); return 0; }
When the above code is executed, it produces the following result
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 <iostream> #include <conio.h> using namespace std; int main() { int i,j,rows;//variable declaration for integer char ch; //Declare a character variable cout<<"Enter the number of rows\n"; //Ask input from the user cin>>rows; //Reading the input value cout<<"Enter the Symbol for pattern\n"; //Ask input from the user cin>>ch; //Reading the symbol for pattern cout<<"\n"; i=1; do{//outer for loop j=1; do{//inner for loop cout<<" ";//print space j++; } while(j<=i); j=1; do{//inner for loop if(i==1 || i==rows || j==1 || j==rows){ cout<<ch;//print characters after space } else{ cout<<" ";//print space } j++; } while( j<=rows); cout<<"\n";//move to next line i++; }while(i<=rows); getch(); return 0; }
When the above code is executed, it produces the following result
