Cpp program to print diamond star pattern
Cpp program to print diamond star pattern
In this tutorial, we will discuss Cpp program to print diamond star pattern.
In this post, we display two diamond patterns using nested for loop and nested while loop in C++ language
In the first program, we are going to learn how to displayed diamond star pattern using for loop or nested for loop in C++ programming language
here, we display a diamond pattern program with coding using nested for loop and also we get input from user using Cin in C++ language
the user can provide numbers as they wish and get the Diamond star pattern according to their input
Program 1
diamond star pattern 1
#include <iostream> #include <conio.h> using namespace std; int main() { int rows,i,j,Num_Of_space=1; cout<<"Enter the number of rows: "; cin>>rows; Num_Of_space=rows-1; for(i=1; i<=rows; i++){ //outer for loop 1 for(j=1; j<=Num_Of_space; j++)//inner for loop for space cout<<" "; Num_Of_space--; for(j=1; j<=2*i-1; j++)//inner for loop for star cout<<"*"; cout<<"\n"; } Num_Of_space=1; for(i=1; i<=rows-1; i++){//outer for loop 2 for(j=1; j<=Num_Of_space; j++) cout<<" ";//inner for loop for space Num_Of_space++; for(j=1; j<=2*(rows-i)-1; j++)//inner for loop for star cout<<"*"; cout<<"\n";//move to next line } getch(); return 0; }
When the above code executed, it produces the following results
Enter the number of rows: 6 * *** ***** ******* ********* *********** ********* ******* ***** *** *
Diamond pattern using while loop
In the second program, we are going to learn how to displayed diamond star pattern using while loop or nested while loop in C++ programming language
here, we displayed a diamond pattern program with coding using nested while loop and also we get input from user using Cin() function in C++ language
the user can provide numbers as they wish and get the Diamond star pattern according to their input
Program 2
diamond star pattern 2
#include <iostream> #include <conio.h> using namespace std; int main() { int i=1,j=1,rows; cout<<"Enter the mnumber of rows\n"; cin>>rows; int space=rows-1; while(j<=rows){ //outer while loop 1 cout<<"\n"; j=1; while(j<=space){ //inner while loop for space cout<<" "; j++; } j=1; while(j<=2*i-1){//inner while loop for star cout<<"*"; j++; } i++; space--; } i=rows-1; space=1; while(i>=1){ //outer while loop 2 cout<<"\n"; j=1; while(j<=space){ //inner while loop for space cout<<" "; j++; } j=1; while(j<=2*i-1){//inner while loop for star cout<<"*"; j++; } i--; space++; } getch(); return 0; }
When the above code executed, it produces the following results
Enter the number of rows: 6 * *** ***** ******* ********* *********** ********* ******* ***** *** *
