Question

define statement must be declared before (in c programming)

Answer 1

Answer:

In C and C++, variables need to be declared before they are used, usually at the beginning of the function before any executable statement. However in python, they need not be declared. And both C++ and python are object oriented

Answer 2

In C and C++, variables need to be declared before they are used, usually at the beginning of the function before any executable statement.

Explanation:

Actually, it is not required that a function be declared before use in C.

If it encounters an attempt to call a function, the compiler will assume a variable argument list and that the function returns an int.

The main difference between declaration and definition in C is that the declaration of a variable indicates the compiler of the existence of a variable, while the definition of a variable indicates the compiler where and how much storage to create for a variable.
