大于和小于特定数字的IF语句

Question

I have a project where I have to create a tax application. I have two integers: gross and taxrate. When the user inputs his gross income, I want it to multiply the certain percentage of the tax rate in his bracket for the tax due. My code is the following:

if (gross < 9075) {
    taxrate = (int) (gross * .10);
}
else (gross > 9075 && < 36900) {
    taxrate = (int) (gross * .15);
}

It tells me there is an error, so I assume I am messing up somewhere. Is there a way to create a proper if statement that goes between two numbers?

Answer 1

You must explicitly state both operands to any binary operator, including comparison operators. Try

} else if (gross > 9075 && gross < 36900) {

Incidentally you may need to consider the case of exactly 9075 , either with

if (gross <= 9075){

OR

} else if (gross >= 9075 && < 36900) {

Answer 2

It looks like you are using a conditional with the else statement, and not using your operators correctly. You want to change this to

else if (gross > 9075 && gross < 36900)

Notice I have changed else to else if and changed the conditional to have the comparisons done correctly.

Answer 3

Try giving it as

taxrate = (int) (gross*0.10f);

and

 taxrate = (int) (gross*0.15f);
