    No, to put that line in words:
    "Declare three variables of type int, with names firstNumber, secondNumber and sumOfTwoNumbers"

    This is a declaration.
    int a;

    This is an initialization.
    int a = 0;
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Totally out of topic but this brings out a question I have about a silly, in my eyes, rule they have at my school: not to initialize a variable during declaration, e.g int i = 0.
    Is there any particular reason why this could be considered a wise practice or is it just trolling on their part to make us waste lines -there's a 25 line limit per function...

    You're right, your school is bone-head stupid not to allow initialisation of variables.

    The world is knee deep in problems caused by uninitialised variables.
    CVE -Search uninitialized

    Back in the mists of time, when compilers were dumb and computers were slow, initialisation cost something.

    But modern compilers will optimise out initialisations if you subsequently assign another value without using the first value.
    Plus the compilers (and tools like Coverity and Klocwork) are very good at finding 'use before initialisation' issues.

    > there's a 25 line limit per function...
    At least they're getting something right.
