FAQs on What is a Function? Video Lecture - Quantitative for GMAT

1. What is a function in programming?

A function in programming is a block of code that performs a specific task. It takes input parameters, performs operations, and usually returns a value. Functions are used to organize code into reusable modules, making the code more efficient and easier to maintain.

2. How do functions work in programming?

In programming, functions are defined with a name, input parameters, and a body that contains the code to be executed. When a function is called, the input parameters are passed, and the code inside the function is executed. The function may return a value or perform a task without returning anything.

3. Can functions in programming have multiple input parameters?

Yes, functions in programming can have multiple input parameters. Input parameters are specified within the parentheses after the function name, separated by commas. These parameters allow the function to receive different values each time it is called, making it versatile and adaptable to various scenarios.

4. What is the difference between a function call and a function definition?

A function call is when a function is invoked or executed in a program, using its name followed by parentheses. It passes any required input parameters and may receive a returned value. On the other hand, a function definition is the actual implementation of the function, where its name, input parameters, and code are specified. It defines what the function does when it is called.

5. Can functions in programming return multiple values?

In some programming languages, functions can return multiple values. These languages provide special syntax or data structures to handle multiple return values. For example, in Python, a function can return multiple values as a tuple. By returning multiple values, functions can provide more information or results to the caller, enhancing the flexibility of the program.
