Write a program that reads a number and displays the above pattern.

#include<stdio.h>
#include<conio.h>

void main()
{
	int N, i, j;
	do{
		printf("Enter N: ");
		scanf("%d",&N);
	}while(N<=0);

	for(i=1; i<2*N; i++)
    	{
		for(j=1; j<=(i/N)*(-1)*(2*N-2*i)+N-i; j++)
            		printf(" ");

        	for(j=1; j<=(i/N)*( 4*N-4*i) + 2*i-1; j++)
            		if(j==1  ||   j== (i/N)*( 4*N-4*i) + 2*i-1)
            			printf("*");
            		else
            	    		printf(" ");

       		printf("\n");
    	}

	getch();
