how to print 0,22,000,4444

concept:

 first we have to print spaces which is supposed to be run in the opposite direction so, let run a loop for row(i) in body of i run loop for j .

for printing spaces, we have to run opposite loops so we can use 4-i . we use this because we have to run this loop opposite means in the sense ****,***,**,*. 

if we do not use this concept the loop will print *,**,***,****

below is the code (runs on turbo c++)

#include<stdio.h>

#include<conio.h>

void main()

{

int i,j;

clrscr();

for(i=1;i<=4;i++)

{

for(j=1;j<=4-i;j++)

{

printf(" ");

}

for(j=1;j<=i;j++)

{

if(i%2==0)

{

printf("%d ",i);

}

else

{

printf("0 ");

}

}

printf("\n");

}

getch();

}
