FAQs on Problem Set: Functions - 2 Video Lecture - Quantitative for GMAT

1. What is a function in programming?
Ans. A function in programming is a reusable block of code that performs a specific task. It takes input arguments, performs operations on them, and returns a result. Functions help in organizing code, making it more modular and easier to read and maintain.
2. How do you define a function in the programming language mentioned in the article?
Ans. In the programming language mentioned in the article, a function is defined using the "def" keyword followed by the function name, a set of parentheses for optional input parameters, and a colon. The function body is indented and contains the code to be executed when the function is called.
3. What is the purpose of a return statement in a function?
Ans. The return statement in a function is used to specify the value or values that the function should output when it is called. It allows the function to provide a result that can be used by the calling code. The return statement also terminates the function, returning control to the caller.
4. Can a function have multiple return statements?
Ans. Yes, a function can have multiple return statements. When a return statement is encountered in a function, the function immediately exits and returns the specified value. Having multiple return statements allows for different conditions or branches of code to return different values, depending on the logic within the function.
5. What is the difference between parameters and arguments in a function?
Ans. Parameters and arguments are related to the input of a function. Parameters are the variables used in the function's definition, while arguments are the actual values passed to the function when it is called. Parameters act as placeholders for the arguments and define the number, type, and order of the required inputs. Arguments, on the other hand, are the specific values that are passed to the function when it is invoked.
