Chapter 5, Problem 1MC

A group of statements that exist within a program for the purpose of performing a specific task is a(n) __________.

a. block

b. parameter

c. function

d. expression

Program Description Answer

A function is a group of statements that are present in a program in order to perform specific tasks.

Hence, the correct answer is option “C”.

Explanation of Solution

Function:

• A function is a group of statements that are present in a program in order to perform specific tasks.
• A function is used to reduce complexity of a program. Instead of writing a large complex program, it can be divided into small chunks, each one performing a particular part of the task.
• The approach of dividing a program into smaller chunks is called as “divide and conquer” because a large program is divided into smaller tasks that can be easily performed.
• A function is also called as module.
• A single program contains more than one function.

Syntax:

In Python, a function is written as follows:

#Function name

def function_Name(parameters):

         #statements

Explanation for incorrect options:

A block is a piece of program which is executed as a unit in a function.

Hence, option “A” is wrong.

A parameter is a part of the program where the information is sent from one function to other function.

Hence, option “B” is wrong.

An expression contains operators, operands, and values in a combined form and they are evaluated.

Hence, option “D” is wrong.
