Chapter 3, Problem 1MC

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

1. a. block
2. b. parameter
3. c. module
4. d. expression

Program Description Answer

A module is a group of statement that is present in a program in order to perform specific tasks.

Hence, the correct answer is option “C”.

Explanation of Solution

Module:

• A module is a group of statement that is present in a program in order to perform specific tasks.
• Module 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 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.
• Module is also called as function.
• Single program contains more than one module.

Syntax:

In Python, function is written as;

#Function name

def function_Name(parameters):

#statements

Explanation for incorrect options:

Block:

Block is a piece of program which is executed as a unit in a module.

Hence, the option “A” is wrong.

Parameter:

Parameter is a part of program, where the information is sent from one module to other module.

Hence, option “B” is wrong.

Expression:

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

Hence, the option “D” is wrong.
