C Programming Midterm Exam

Who developed the C programming language?

• Bjarne Stroustrup

• James Gosling

• Dennis M. Ritchie

• Guido van Rossum

Which of the following statements about the C programming language is true?

• C was introduced in the early 1970s and is the successor of the A language.

• C is a successor of the B language and was formalized by the International Organization for Standardization (ISO) in 1988.

• C is a successor of the B language, introduced around the early 1970s, and was formalized in 1988 by the American National Standard Institute (ANSI).

• C was formalized in 1988 by the American National Standard Institute (ANSI) and is a predecessor of the B language.

Why was the C programming language initially adopted for system development work?

• Because it was the only available language for operating system development.

• Because it was designed specifically for application software development.

• Because it produces code that runs efficiently, making it ideal for system development, particularly for the programs that make up the operating system.

• Because it was created as a high-level language for business applications.

What does a flowchart represent in the context of programming?

• A textual description of a program's code.

• A diagrammatic representation of the sequence of logical steps in a program, using geometric shapes to depict processes and arrows to show relationships and data flow.

• A tool for debugging and testing software.

• A list of variables and their values used in a program.

Which of the following is true about identifiers in the C programming language?

• Identifiers can start with a digit.

• C allows punctuation characters such as @, $, and % within identifiers.

• C is not case sensitive, so Manpower and manpower are considered the same identifier.

• Identifiers must start with a letter or an underscore, followed by letters, digits, or underscores, and C is case sensitive.

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 operator precedence in the context of the C programming language?

• The rule that specifies the order in which operators with the same precedence level are evaluated.

• The ability to override operators within an expression.

• The grouping of terms in an expression that determines the order of evaluation, where certain operators have higher precedence and are evaluated first.

• The process of converting operators into functions.

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.
