C Programming Concepts final Examination

What is an operator in the context of the C programming language?

• A keyword that defines a data type.

• A symbol that instructs the compiler to perform specific mathematical or logical functions, with various types like Arithmetic, Relational, Logical, Assignment, and Miscellaneous operators.

• A function that only performs mathematical calculations.

• A special variable that stores values.

What is the purpose of decision-making structures in programming?

• To repeat a block of code multiple times.

• To define functions and variables in a program.

• To specify conditions that are evaluated by the program, determining which statements are executed based on whether the conditions are true or false.

• To import libraries and modules into a program.

What is the purpose of a loop statement in programming languages?

• To define the start and end of a program.

• To execute a statement or group of statements only once.

• To execute a statement or group of statements multiple times, allowing for more complicated execution paths.

• To declare variables and constants.

What does a while loop do in C programming?

• It executes a target statement once, regardless of the condition.

• It repeatedly executes a target statement as long as a given condition is true.

• It executes a target statement only if the condition is false.

• It executes all the statements in a program simultaneously.

In the context of loops, what does 'nested loop' mean?

• A loop that runs indefinitely

• A loop that is executed once

• A loop inside another loop

• A loop that does not execute

Which of the following is NOT a type of loop in C programming?

• For Loop

• Repeat Until Loop

• While Loop

• Do While Loop

In a while loop, when does the control pass to the line immediately following the loop?

• When the condition becomes true

• When the loop body is executed

• When the condition becomes false

• When the loop is nested

What is the output of the following code: 'while(i >= 1) { printf("%d\n", i); i--; }' when i starts at 9?

• 9 8 7 6 5 4 3 2 1 0

• 0 1 2 3 4 5 6 7 8 9

• 9 8 7 6 5 4 3 2 1

• 1 2 3 4 5 6 7 8 9

Which loop type tests the condition before executing the loop body?

• Do While Loop

• While Loop

• Nested Loop

• For Loop

What is the primary purpose of a loop in programming?

• To execute a block of code multiple times

• To define a function

• To create a user interface

• To store data temporarily
