Answer 1

Solution.

This is my approach for solving the question.

#include <stdio.h>

#include <stdlib.h>

int main() {

   int n=9,i,j;

   for(i=1-n;i<=n-1;i+=2){

       for(j=1;j<=n-abs(i);j++){

           if(j%2==1)

               printf("%d",j);

           else

               printf("*");

       }

       printf("\n");

   }

   return 0;

}

Output.
