Calculating Monthly Salary with Doubling Formula

[remaan]

Homework Statement

In this problem, we are asked to write a program which displays the salary of a person for one month. Given that his salary for the first day is 1, second day 2 $ , third day 4$ , and contiue to double . And, then we have to display the total salary of the whole month.

The Attempt at a Solution

Her is the code I made

public class Ass3 {

public static void main (String args [])
{

int salary = 1;

System.out.println(salary);

for ( int d = 0 ; d < 29 ; d++)

{
salary *=2;
System.out.println(salary);

}


}

}

I tired with making total = 0 and then total = total + salary,
But it did Not work, even when putting inside the loop itself ?

What do you think ?

Go through the days of the month and each day work out the salary for that day and a running total up to the end of that day.

At the end of the month you have a month's salary in the total.

what do you mean by : a running total up to the end of that day ?

What I thought about is initlizing a variable total = 0

and then add the salaries each day.

Right ??

 

[vk6kro]

Yes, that is right.
Each day double the previous day's salary and add it to the total.

Before you start the loop, make the total = 0, the first day's salary = 1.
Then FDS= FDS * 2
Total = total + FDS

Be ready for a very big number.
