Question

________ functions may have the same name, as long as their parameter lists are different.

A) Only two
B) Two or more
C) Zero
D) Un-prototyped
E) None of these

Answer 1

Functions or methods can have the same name if their parameter lists are different, a concept known as function or method overloading. Overloaded functions provide flexibility and enhance code readability by allowing the same function name to perform different actions based on the input parameters.

Step-by-step explanation:

The correct answer is B) Two or more. In many programming languages, functions or methods may have the same name as long as their parameter lists are different. This concept is known as function overloading or method overloading. It allows a class to have multiple methods with the same name but different parameters.

For example, consider a class that has two overload methods to add numbers, where one takes two integers and another takes three integers:

• int add(int a, int b)
• int add(int a, int b, int c)

Despite having the same name, these methods are treated as distinct because their parameter lists are different. This overloading feature enables methods to be called based on the parameter list passed during the method call, which enhances the flexibility and readability of the code.
