Program to print Swastika Pattern

Given the number of rows and columns, print the corresponding swastika pattern using loops. 

Note: The number of rows and columns should be the same and an odd number. This will generate a perfect swastika pattern. 

Examples :

Input : row = 7, column = 7        
Output:
*     * * * *
*     *
*     *
* * * * * * *
      *     *
      *     *
* * * *     *

Input : row = 11, column = 11
Output :
*         * * * * * *
*         *
*         *
*         *
*         *
* * * * * * * * * * * 
          *         * 
          *         * 
          *         * 
          *         * 
* * * * * *         * 

Below is the implementation to print the swastika pattern. 

C++

// C++ implementation to
// print swastika pattern
#include <bits/stdc++.h>
using namespace std;

// function to print swastika
void swastika(int row, int col)
{
for (int i = 0; i < row; i++) {
    for (int j = 0; j < col; j++) {

    // checking if i < row/2
    if (i < row / 2) {

        // checking if j<col/2
        if (j < col / 2) {

        // print '*' if j=0
        if (j == 0)
            cout << "*";

        // else print space
        else
            cout << " " << " ";
        }

        // check if j=col/2
        else if (j == col / 2)
        cout << " *";
        else
        {
        // if i=0 then first row will have '*'
        if (i == 0)
            cout << " *";
        }
    }
    else if (i == row / 2)
        cout << "* ";
    else {

        // middle column and last column will have '*'
        // after i > row/2
        if (j == col / 2 || j == col - 1)
        cout << "* ";

        // last row
        else if (i == row - 1) {

        // last row will be have '*' if
        // j <= col/2 or if it is last column
        if (j <= col / 2 || j == col - 1)
            cout << "* ";
        else
            cout << " " << " ";
        }
        else
        cout << " " << " ";
    }
    }
    cout << "\n";
}
}

Time Complexity: O(row * col), where row and col represents the given number of rows and columns.
Auxiliary Space: O(1), no extra space is required, so it is a constant.
