One-liner if statements, how to convert this if-else-statement

Question

Total noob here so be gentle. I\'ve looked everywhere and can\'t seem to find the answer to this. How do I condense the following?

if (expression)
{
    re         


        

Answer 1

Since expression is boolean:

return expression;

Answer 2

All you'd need in your case is:

return expression;

The reason why is that the expression itself evaluates to a boolean value of true or false, so it's redundant to have an if block (or even a ?: operator).

Answer 3

If expression returns a boolean, you can just return the result of it.

Example

 return (a > b)

Answer 4

return (expression) ? value1 : value2;

If value1 and value2 are actually true and false like in your example, you may as well just

return expression;
