You did not say what language your assignment is supposed to be in.
So answers cannot be direct.
I suggest that you start by:
0. Given a salary amount (collect a salary amount from the user or a
file)
1. tax is calculated by adding the base tax for that salary range
(lookup base tax from a table)
2. and the product of percentage of excess (lookup % excess from your
table)
3. and the amount of salary over the minimum salary for that range.
(lookup amount over the minimum)
4. Calculate the number given these 4 facts.
That takes care of this:
· Design a program that solves this problem.
Your sample table gives you 10 test values. Try some others.. just
use your head. That handles this:
· Generate a set of input test values.
Show that the program works. That handles this:
· Perform a design walkthrough to verify your design.- Hide quoted text -
- Show quoted text -
There's no specific language. This class is just beginning
programming. It's called "Fundamentals of programming with algorithms
and logic."
Is this correct?
#include <iostream>
using namespace std;
int main(int argc, char **argv){
double salary;
double taxrate;
double tax;
//get input
cout<<"Enter Salary: ";
cin >> salary;
//compute tax and type of salary
if(salary >=0 && salary <1500){
tax = salary * 0.15;
cout<<"Salary is: $" << salary<<endl;
cout<<"Tax is: $"<<tax <<endl;
cout<<"Net Salary is: $"<< (salary - tax)<<endl;
}
else if(salary >=1500 && salary <3000){
tax = 225.0;
double x = salary - 1500;
tax += x * 0.16;
cout<<"Salary is: $" << salary<<endl;
cout<<"Tax is: $"<<tax <<endl;
cout<<"Net Salary is: $"<< (salary - tax)<<endl;
}
else if(salary >=3000 && salary < 5000){
tax = 465.0;
double x = salary - 3000;
tax += x * 0.18;
cout<<"Salary is: $" << salary<<endl;
cout<<"Tax is: $"<<tax <<endl;
cout<<"Net Salary is: $"<< (salary - tax)<<endl;
}
else if(salary >=5000 && salary <8000){
tax = 825.0;
double x = salary - 5000;
tax += x * 0.20;
cout<<"Salary is: $" << salary<<endl;
cout<<"Tax is: $"<<tax <<endl;
cout<<"Net Salary is: $"<< (salary - tax)<<endl;
}
else if(salary >=8000 && salary <15000){
tax = 1525.0;
double x = salary - 8000;
tax += x * 0.25;
cout<<"Salary is: $" << salary<<endl;
cout<<"Tax is: $"<<tax <<endl;
cout<<"Net Salary is: $"<< (salary - tax)<<endl;
}
system("pause");
return 0;
}
No, I'm afrid you've haven't really understood.
The program needs to read a table of salaries and tax rates from an input file.
If you are implementing in C++ unfortunately it is hard to give an answer because there are so may styles of C++ programming.
Basically you need
#define MAXBRACKET 1000
We can assume that no mad bureaucrat would ever have over 1000 tax bands.
double minsal[MAXBRACKET];
double maxsalary[MAXBRACKET];
doube taxrate[MAXBRACKET];
int Nbrackets;
So we set up this global array, and read the values from the table into it.
So Nbrackets will be set to the number of data lines in the table (read until you get an EOF, incrementing each time).
As a test, print out these arrays to make sure you have read them in correctly.
Then it is a simple matter of taking the salary, stepping through the array until you are greater than or equal to the minimum and less than or equal to the maximum. Then apply your tax formula.
