How to Create Function in C++?
There are many built-in functions, but sometimes you might need to write a custom one.
main.cpp
12345// Function to add two numbers int add(int a, int b) { return a + b; }
The function signature provides essential information about a function's interface, including its name, return type, and parameter list.
Specifies the type of data the function will return. For example, int indicates the function will return an integer value.
A unique identifier for the function, used to call it from other parts of the program.
Defines the input values the function expects. For example, a function might expect a single integer parameter named n.
Contains the code that performs the desired operations, enclosed in curly braces {}.
Specifies the value the function will return to the caller using the return keyword.
Thus, above, we described the structure of a function in C++: any function consists of a signature, a function body, and a return value.
