Personal Deductions:
Single = 9, 000.00
Head of the Family = 12, 000.00
Married = 18, 000.00
Additional Deduction / Exemption:
8, 000.00 / dependent
Note: Maximum of four (4) dependents
TAX TABLE
TAXABLE INCOME TAX DUE
<= 2, 500.00 0%
> 2, 500.00 && <= 5, 000.00 1%
> 5, 000.00 && <= 10, 000.00 25.00 + 3% of excess over 5,000.00

INPUT REQUIREMENT:
1. Name of Taxpayer
2. TIN (Tax Identification Number)
3. Gross Income (Annual Income)
4. Civil Status (Single, Married, or Head of the Family)
5. Number of Dependents
PROCESS:
1. Get the name of Taxpayer, his/her TIN and Gross Income.
2. Get the Civil Status
3. If Civil_Status != “Single”, get the number of dependents.
4. Compute for the taxable income.
a. Taxable Income = Gross Income – Total Exemption
b. Total Exemption = Personal Deduction + Additional Exemption
5. Get the tax due.
PROGRAM SPECIFICATION:
1. Include necessary validation codes.
2. Use at least three (3) functions.
a. To get the Personal Deduction.
b. To get the Additional Exemption.
c. To get the tax due.
3. Use a loop. This would allow the user to execute the program as many times as the user wants to.


my question is:

1.) how should i use the functions?
2.) what header file/s will i use?

i'm having a hard time coding this.thanks

read program specification

Hey, i'm still having a hard time..i dont know where to start

if that's C++... you should first include <iostream>.. you can include other header files if you need them.

second.. follow what the program specification says.. It says that you need to use at least 3 functions.. so..

PersonalDeduction(parameters here..)
{ 
     your codes here..
}
AdditionalExemption(parameters here...)
{
     your codes here.. 
}
TaxDue(parameters here...)
{
     your codes here.. 
}

and your main().....


you can add another function if you need it... and it says you need to use for loop somewhere inside those functions...

read the process requirement.. good luck...

Well i didn't start coding but what i did is the loop

char ans;
do
{
 codes here....
}
cout<<"do you want to continue? [y/n]";
}while ( ans == 'Y' || ans == 'y');
{
cout<<"thank you!";
}


btw, how should i use functions..i read everything about it but i just don't get it..

for example... a function that returns a int..

int foo ()
{
return 5;
}


void main()
{
cout << foo() << endl;

int x = foo();

cout << x << endl;
}






/////////////////


Functions are basically to isolate parts of code. If you will use the same code several times, wop!! you should put it in a function! ;)


Start from there =)

Okay so i finished coding..thanks for helping

BUT..i cant run my code because of several problems and i dont know why

that's my code( long isn't it?) the error says:

"invalid operands of types `double' and `<unknown type>' to binary `operator<<'
