Total money for day 3 is Rs. 0.80
Total money for day 4 is Rs. 1.60
………….

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
main()
{
 int i;
 float x=0.20;
 printf("Total money for day 1 = Rs.0.20\n");
 for(i=1;i<=15;i++)
 {
  x = (x*2);
  printf("Total money for day %d = %f\n",i,x);
 }
 system("pause");
}
