Question: 1 / 565

What does a function prototype in C++ provide information about?

The function's return type only

The number and types of arguments

A function prototype in C++ provides information about the number and types of arguments that a function takes in. This allows for proper function calling and error checking. The return type of the function is not the only information provided by the prototype, so option A is incorrect. The libraries required by the function are not included in the function prototype, so option C is also incorrect. Lastly, a function prototype does not provide information about the source code of the function, as it only declares the function and its parameters, making option D incorrect.
