Give a reusable set of instructions a name, call it when needed, and optionally get a result back.
A function is a named group of instructions you can use again without rewriting them.
You can give a function information to work with, called parameters. The function can SEND a result BACK to the code that called it.
This action accepts two numbers, adds them, and sends the result back.
ACTION AddNumbers WITH firstNumber, secondNumber
CREATE result AS firstNumber + secondNumber
SEND result BACK
END ACTION
CREATE total AS CALL ACTION AddNumbers WITH 4, 6
SHOW totalPython defines a function with def and sends a result back with return.
def addNumbers(firstNumber, secondNumber):
result = firstNumber + secondNumber
return result
total = addNumbers(4, 6)
print(total)JavaScript uses function and return for the same reusable helper.
function addNumbers(firstNumber, secondNumber) {
const result = firstNumber + secondNumber;
return result;
}
const total = addNumbers(4, 6);
console.log(total);C# declares the parameter types and the type of value the method returns.
static int AddNumbers(int firstNumber, int secondNumber)
{
int result = firstNumber + secondNumber;
return result;
}
int total = AddNumbers(4, 6);
Console.WriteLine(total);Java uses typed parameters and return values in a similar way.
static int addNumbers(int firstNumber, int secondNumber) {
int result = firstNumber + secondNumber;
return result;
}
int total = addNumbers(4, 6);
System.out.println(total);C++ also declares the input and return types.
int addNumbers(int firstNumber, int secondNumber)
{
int result = firstNumber + secondNumber;
return result;
}
int total = addNumbers(4, 6);
std::cout << total << '\n';
