    No, if you specify void, it simply means that it requires no argument and would be equivalent to second form. And yeah, the first function would be void getdata(void) not Void getdata(void)

    Remember C/C++ is case sensitive.

    I would first like to know how come this display() function can accept any no. of arguments in C?
    Are you sure? This action cannot be undone.

    i read somewhere that in C,if a function declared with an empty parentheses then in function definition we can pass any number of arguments.i want to know that is true in c++?

    Your concepts are absolutely wrong!

    Please tell me more about this Declaration and Definition thing.

    See, you declare a function so as to tell the compiler that this particular kind of function would be used.

    You define it, in order to implement the logic you want that module to execute.

    Empty parentheses means no arguments, and hence if declaration says your function would have no argument, then how can you define a function with arguments?

    It's just like saying Hello, My name is Mansi, I don't use internet.

    Then somewhere in definition you say, Hello My name is Mansi, I use CrazyEngineers.

    The declaration and definition goes hand in hand.

    PS: Please keep this explanation this time, I've my exams I would clear this entire thing after 10th! 😁

    Till then, why don't you use Google 😀
