In this post, we will write a C++ program to print the diamond patterns of stars. the first user will enter the number between 1 to 25 and then the program will print the star pattern based on the number.
C++ program to print diamond patterns of stars
#include<iostream>
#include<conio.h>
#include<windows.h>
BOOL gotoxy(const WORD x, const WORD y) {
COORD xy;
xy.X = x;
xy.Y = y;
return SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), xy);
}
int main()
{
system("cls");
int i,j,k,l,n;
std::cout<<"Enter the number of star b/w 1 to 25 = ";
std::cin>>n;
system("cls");
if(n <= 25)
{
for(i=1;i<=n;i++)
for(j=(n+1)-i;j<=i;j++)
{
gotoxy(i+i-n,j);
std::cout<<"*";
}
for(k=n;k>=1;k--)
for(l=k;l<=(n+1)-k;l++)
{
gotoxy(k+k+(n-2),l);
std::cout<<"*";
}
}
else
std::cout<<"The number you enter is greater than 25 ";
getch();
return 0;
}
Output
Enter the number of star b/w 1 to 25 = 25
