Overloading refers to a concept within computer programming that allows multiple functions with the same name to exist but with different sets of parameters or argument types. This concept enables programmers to create functions that perform similar tasks or operations but with different inputs or variations. By overloading functions, programmers can provide flexibility and convenience to users by allowing them to invoke the same function name with different argument types or quantities based on their specific requirements.
When a program calls an overloaded function, the compiler determines which specific version of the function to execute based on the argument types or the number of arguments provided. This process is known as function overloading resolution.
In overloading, functions must have the same name but differ either in the number of parameters or their types. The return type does not affect function overloading. By providing variations of a function, programmers can enhance code readability, reduce duplication, and ensure code reusability.
Overloading can be particularly beneficial in scenarios where a function performs similar tasks but with different data types or where default values are provided for some arguments. By taking advantage of function overloading, developers can create more efficient and concise code that caters to a wider range of user needs.

The word "overloading" originates from the verb "overload", which was formed by combining the prefix "over-" with the base word "load". The prefix "over-" suggests excess or exceeding, while "load" refers to the burden or weight that is being carried or placed. When this verb is used in the context of programming or computing, "overloading" describes the act of assigning multiple meanings or functions to a single operator or function name, hence creating an excess of possibilities or burdens for that particular element.
