We can make Diamond pattern in using C++ programming #include<iostream.h> #include<conio.h>
void main() { int n, c, k, space = 1; clrscr(); cout<<"\n\nEnter number of rows: "; cin>>n; space = n - 1;
for (k = 1; k<=n; k++) { for (c = 1; c<=space; c++) cout<<" ";
space--;
for (c = 1; c<= 2*k-1; c++)
cout<<"*";
cout<<"\n";
}
space = 1;
for (k = 1; k<= n - 1; k++) { for (c = 1; c<= space; c++) cout<<" ";
space++;
for (c = 1 ; c<= 2*(n-k)-1; c++)
cout<<"*";
cout<<"\n";
} getch(); }
