    increment operator syntax

    Hello all,

    New to the forum and C++. I am not entirely clear on the proper usage of increment operators.

    What means x = x +1?

    x++

    or

    ++x?

    Also, which one means "get current value of x"?

    thank you so much in advanced

    x++

    If you use them as stand-alone statements: both. Otherwise: neither.

    Neither. If you want x, write x. However, if you are using an increment operator in a larger expression and want the current value of x, then post-increment (x++) makes sense.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
