Cpp program to Display diamond number pattern using while loop
In this tutorial, we will discuss the concept of Cpp program to Display diamond number pattern using while loop
In this post, we will learn how to create diamond number pattern using while loop in C++ language
We can use for loop, while loop or do while loop to display different diamond Number patterns.
Here, we will use while loop to print diamond Number patterns
The following C++ program requests the user to enter the number of rows as the user wanted and the program will display the number of rows in diamond number pattern according to the user input
Program 1
diamond number pattern 1
#include <iostream> #include <conio.h> using namespace std; int main() { int rows; cout<<"Enter the number of rows: "; cin>>rows; int row=1,i,j,k; i=1; while(i<=rows){ //print upper part for(j=1; j<=rows-i; j++){ cout<<" "; } k=1; while(k<=i){ cout<<k;//print number for upper part cout<<" "; k++; } cout<<"\n"; i++; } i=1; while(i<=rows-1){ //print lower part j=1; while(j<=i){ cout<<" "; j++; } k=1; while(k<=rows-i){ cout<<k;//print number for lower part cout<<" "; k++; } cout<<"\n"; i++; } getch(); return 0; }
When the above code is executed, it produces the following result
Enter the number of rows: 6 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 1 2 3 4 5 6 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1
Program 2
diamond number pattern 2
#include <iostream> using namespace std; int main() { int i,j,k,l,rows; cout<<"Enter the number of rows"; cin>>rows; i=1; while(i<=rows){ //print upper part j=1; while(j<=rows-i){ cout<<" ";//print initial space for upper part j++; } k=i; while(k>=1){ cout<<k; k--; } l=2; while(l<=i){ cout<<l; l++; } cout<<"\n"; i++; } i=rows-1; while(i>=1){ //print lower part j=0; while(j<=rows-1-i){ cout<<" ";//print initial space for lower part j++; } k=i; while(k>=1){ cout<<k; k--; } l=2; while(l<=i){ cout<<l; l++; } cout<<"\n"; i--; } return 0; }
When the above code is executed, it produces the following result
Enter the number of rows: 6 1 212 32123 4321234 543212345 65432123456 543212345 4321234 32123 212 1
Program 3
diamond number pattern 3
#include <iostream> #include <conio.h> using namespace std; int main() { int rows,i,j; int row=1; cout<<"Enter the number of rows: "; cin>>rows; i=rows/2; while(i>0){ //print upper part j=1; while(j<=i){ cout<<" "; j++; } j=1; while(j<=row){ cout<<row; cout<<" "; j++; } cout<<"\n"; row++; i--; } i=0; while(i<=rows/2){ j=1; while(j<=i){ cout<<" "; j++; } j=row; while(j>=1){ //print lower part cout<<row; cout<<" "; j--; } cout<<"\n"; row--; i++; } getch(); return 0; }
When the above code is executed, it produces the following result
Enter the number of rows: 8 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 4 4 4 4 3 3 3 2 2 1
