5. Calculate the tax on net income of a person. Rules for calculating tax are
• No tax is paid on first Rs. 15,000 of net income.
• A tax of 5% is assessed on each rupee of net income over Rs. 15,001 to Rs. 25,000.
• A tax of 10% is assessed on each rupee of net income over Rs. 25,000

C++

#include<iostream>
using namespace std;
void main()
{
	int tax, income;
	cout << "please enter your income" << endl;
		if
			(income <= 15000)
			cout << "No Tax on you ! keep enjoying";
		else if
			(income <= 25000)
			tax = (income - 15000)*0.05;
		cout << "Tax=" << tax << endl;
		else
			(income > 25000)
			tax = (1000 * 0.05) + ((income-25000)*0.1);
		cout << "Tax=" << endl;
	system("pause"); 
}
</iostream>

I try but it gives error on visual studio

What have you tried? Where are you stuck?

#include<iostream>
using namespace std;
void main()
{
int tax, income;
cout << "please enter your income" << endl;
if
(income <= 15000)
cout << "No Tax on you ! keep enjoying";
else if
(income <= 25000)
tax = (income - 15000)*0.05;
cout << "Tax=" << tax << endl;
else
(income > 25000)
tax = (1000 * 0.05) + ((income-25000)*0.1);
cout << "Tax=" << endl;
system("pause");
}

Tell your teacher that taxes are not calculated on net income, but on gross income :-) As for the programming task at hand: Just look into your course notes. If you can't do this simple assignment, I would advise to better find another career.

my classes start just 2 weaks ago so please keep your advice to your own !

Assignments are usually in line with the text book or the teachers lecture. So, please look up the solution in your material.
It all starts with formatting. Then you will easily see what is wrong. In addition, learn to read the error message of the compiler. You cannot ask for advise with each and every error message produced. You did not even bother to tell the full error message to us...! Learn to communicate problems properly so that it is easy for us to help. Do you really expect us to run your code to find out what exact error message is produced? This is a *quick* answer forum - not a "gimme code for free" nor "please invest time to do the work for me since I'm too lazy to look the solution up in my text book"...
E.g. check what an if-else statement looks like: if cond statement else statement. What is statement? One single statement or a block. Now it's up to you again...

And what prevents you from debugging your code?

Solution 1

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

First mistake: Your program ask to type the income but never read the keyboard.
second mistake: there is no condition after else, only after if.
You should also read about the usage of {} with if statement.

I have Improved your question

Now tell us what is the error you get and where.

Member 12032240 4-Oct-15 18:06pm

it says illegle else without if

Member 12032240 4-Oct-15 18:07pm

Patrice T 4-Oct-15 18:29pm

You should also read about the usage of {} with if statement.

Solution 2

you are not using { and } that will give you error: illegal else without if

C++

#include<iostream>
using namespace std;
void main()
{
	    int  income;
        float tax;          // make float variable, value may be in decimal points
	    cout << "please enter your income" << endl;
		if(income <= 15000)
        {                               //open {
		    cout << "No Tax on you ! keep enjoying";
        }                               //Close }
		else if(income <= 25000)
        {                               //open {
		    tax = (income - 15000)*0.05;
		    cout << "Tax=" << tax << endl;
        }                               //Close }
		else if(income > 25000) // or you can keep only 'else' without any condition
        {                               //open {
		    tax = (10000 * 0.05) + ((income-25000)*0.1);
		    cout << "Tax=" << endl;
        }                               //Close }
	system("pause"); 
}
</iostream>

Well, you have some points but last else is still incorrect. if you have a condition, then you need an if for that condition. In this case last condition is not needed.

Member 10641779 7-Oct-15 5:25am

Sry, actually I just copied the code and make changes on that. it should have to be else if(conditon) or only else.

phil.o 7-Oct-15 5:33am

Copying code while learning is the worst idea you could have had.
If you want to learn, then really do it, and begin to write your code yourself.
Copying code from anywhere and expecting someone else to customize it to your own need is not a developper's behavior.

Richard MacCutchan 7-Oct-15 6:16am

Don't use floting point in financial calculations, you will end up charging the wrong amounts of tax. See http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html.

Stefan_Lang 12-Oct-15 2:55am

No worries, this sure isn't going to be used in a live system. Live systems would be more like this:
"How much have you earned last year?"
"Send it to us!"
;-P

Just joking - on a more serious note: good advice.
