C++ Program to print Swastika Pattern

In this C++ tutorial, we will see how to print Swastik pattern from given number n, the pattern of n height using loops.

Note- N, an odd number (>=5).

Print Swastik Pattern

Divide the given pattern into two parts from the middle. Now do the work of these parts separately and print the required pattern accordingly.

Examples :

n=7
*     * * * *
*     *
*     *
* * * * * * *
      *     *
      *     *
* * * *     *

Code:

First, we calculate mid because it should be divided into 5 parts – using nested loops.

1. Top line – our loop print top line if(i==1) we print * and then when j>mid.
2. Between Top and Middle – we print *  for only when j==1 and j== mid.
3. Middle line- we print the whole line with *.
4. Between Middle and Bottom – we print * for h== mid and j==n.
5. Bottom Line – we print * for j<=mid

#include<iostream>
using namespace std;
int main(){
    int n=11;
    int mid= (n/2)+1;
    for(int i=1;i<=n;i++){

        //top line
        if(i==1){
            cout<<"* ";
            for(int j=2;j<=n;j++){
                if(j<mid){
                    cout<<"  ";
                }
                else{
                    cout<<"* ";
                }
            }
            cout<<endl;
        }
        //between top and middle
        if(i!=1 && i<mid){
            for(int j=1;j<=n;j++){
                if(j==1 || j==mid){
                    cout<<"* ";
                }
                else{
                    cout<<"  ";
                }
            }
            cout<<endl;
        }
        //middle line
        if(i==mid){
            for(int j=1;j<=n;j++){
                cout<<"* ";
            }
            cout<<endl;
        }
        //between middle and bottom
        if(i>mid && i!=n){
            for(int j=1;j<=n;j++){
                if(j==mid || j==n){
                    cout<<"* ";
                }
                else{
                    cout<<"  ";
                }
            }
            cout<<endl;
            

        }
        //bottom line
        if(i==n){
            for(int j=1;j<=n-1;j++){
                if(j<=mid){
                    cout<<"* ";
                }
                else{
                    cout<<"  ";
                }
                
            }
            cout<<"* ";
            
        }
    }
}

 

Now its time to run our program. So let’s see what we will see after we run the program:

*         * * * * * *
*         *
*         *
*         *
*         *
* * * * * * * * * * * 
          *         * 
          *         * 
          *         * 
          *         * 
* * * * * *         *

We can see that our Swastik pattern done correctly with the C++ program and we can see the result in the console.
