Program to print Inverse Diamond pattern on C++
In this tutorial, we will be discussing a program to print given inverse diamond pattern.
For this, we will be provided with the value of N. Our task is to print an inverse the diamond pattern according to the height of 2N-1.
Example
#include<bits/stdc++.h>
using namespace std;
//printing the inverse diamond pattern
void printDiamond(int n){
cout<<endl;
int i, j = 0;
//loop for the upper half
for (i = 0; i < n; i++) {
//left triangle
for (j = i; j < n; j++)
cout<<"*";
//middle triangle
for (j = 0; j < 2 * i + 1; j++)
cout<<" ";
//right triangle
for (j = i; j < n; j++)
cout<<"*";
cout<<endl;
}
//loop for the lower half
for (i = 0; i < n - 1; i++) {
//left triangle
for (j = 0; j < i + 2; j++)
cout<<"*";
//middle triangle
for (j = 0; j < 2 * (n - 1 - i) - 1; j++)
cout<<" ";
//right triangle
for (j = 0; j < i + 2; j++)
cout<<"*";
cout<<endl;
}
cout<<endl;
}
int main(){
int n = 5;
printDiamond(n);
return 0;
}Output
