#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>

我尝试但它在visual studio上出错

I try but it gives error on visual studio

推荐答案

我们不做你的作业：它是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！

第一个错误：你的程序要求输入收入但从未读过键盘。

第二个错误： else 之后没有条件，只有在之后 c $ c>。

如果 {} 与的使用情况>声明。

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.

你没有使用 {和} 会给你错误：非法的其他没有

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

#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>
