Function vs Procedure with Parameters

What is the main difference between Functions and Procedures?

• Procedures return a value after execution, while Functions do not return any value.

• Functions do not have parameters, while Procedures have parameters.

• Procedures can be called recursively, while Functions cannot be called recursively.

• Functions return a value after execution, while Procedures do not return any value.

Can you provide an example of a Function with Parameters?

• function multiply(x, y) { return x * y; }

• function sum(a, b) { return a + b; }

• function add(num1, num2) { return num1 + num2; }

• function subtract(num1, num2) { return num1 - num2; }

Can you provide an example of a Procedure with Parameters?

• calculateArea(length, width)

• findArea(length, width)

• calculateArea(size)

• calculateArea(width, length)

In what way do Functions with Parameters differ from Procedures with Parameters?

• Functions with Parameters can be called multiple times, while Procedures with Parameters can only be called once.

• Functions with Parameters can modify the input values, while Procedures with Parameters cannot.

• Functions with Parameters return a value after execution, while Procedures with Parameters do not return any value.

• Functions with Parameters do not accept any input values, while Procedures with Parameters do.

Why are Parameters important in Functions and Procedures?

• Parameters are unnecessary and complicate the code

• Functions and Procedures cannot accept Parameters

• Parameters enable passing data into functions and procedures, enhancing reusability and flexibility.

• Parameters limit the functionality of Functions and Procedures

What is the purpose of a return statement in a Function?

• To stop the function from executing

• To confuse the user

• To specify the value that the function should output when it is called.

• To increase the complexity of the code

When should you use a Procedure instead of a Function?

• When you need to perform an action without returning a value.

• When you need to perform an action and return a value.

• When you need to use a built-in function instead.

• When you need to return a value without performing an action.

Explain the concept of passing arguments to Functions and Procedures.

• Passing arguments always results in errors

• Passing arguments involves defining new variables within the function or procedure

• Passing arguments is not necessary in programming

• Passing arguments involves supplying values to the parameters defined in the function or procedure declaration, allowing the code to work with specific data during execution.

What happens when a Function is called in a program?

• The program execution jumps to the function definition, executes the code inside the function, and then returns to the point where the function was called.

• The program execution halts and does not proceed further

• The function definition is deleted from the program

• The program crashes and displays an error message

How do you declare a Function in a programming language?

• method functionName(parameters) { // function body }

• def functionName(parameters) { // function body }

• func functionName(parameters) { // function body }

• function functionName(parameters) { // function body }
