wap to print the following pattern.

#include<stdio.h>
void main()
{
int i,j,k,a=1,b=1,n;
printf("enter the number of rows");
scanf("%d",&n);
for(i=n;i>=1;i--)
 {
   {
    for(j=1;j<=i-1;j++)
    printf("  ");
    for(k=1;k<=b;k++)
    if((k&1)==0)
    printf("  ");
    else
    printf("%c ",'a');
    }

  b=b+2;
  printf("\n");
  }
}

NOTE-  i have compiled this program in codeblocks if u do it in turbo c++  use  conio.h  header file in the beginning  and getch()  a the  last
