Fundamentals of C Programming

What is the history of C programming?

• C programming was developed in the early 1970s by Dennis Ritchie at Bell Labs.

• C programming was developed by Microsoft for Windows.

• C programming was created in the 1980s by Bjarne Stroustrup.

• C programming is a high-level language developed in the 1960s.

Describe the structure of a C program.

• A C program includes only variable declarations and no functions.

• A C program is structured as a single line of code.

• A C program consists only of comments and whitespace.

• A C program structure includes preprocessor directives, the main function, variable declarations, executable statements, and additional functions.

What are pre-processor directives in C?

• Pre-processor directives are part of the C runtime library.

• Pre-processor directives are used for memory management in C.

• Pre-processor directives are commands for the C pre-processor that manage file inclusion, macro definitions, and conditional compilation.

• Pre-processor directives are commands that execute at runtime.

List the different data types available in C.

• int, float, double, char, void

• array

• boolean

• string

Explain the concept of constants and variables in C.

• Both constants and variables can be modified during program execution.

• Variables are used for memory allocation, and constants are for data types.

• Constants are fixed values that cannot change, while variables are storage locations that can hold different values.

• Constants can change values at runtime, while variables are fixed.

What are operators in C and how are they used?

• Operators in C are only applicable to integer data types.

• Operators in C are reserved keywords that cannot be changed.

• Operators in C are symbols that perform operations on variables and values, used in expressions for calculations, comparisons, and control flow.

• Operators in C are only used for arithmetic calculations.

Define operator precedence and associativity.

• Operator precedence is only relevant in programming languages.

• Associativity refers to the number of operators in an expression.

• Operator precedence determines the data type of variables.

• Operator precedence is the order of operations in expressions, while associativity is the direction of evaluation for operators of the same precedence.

What is decision making in C programming?

• Decision making in C programming refers to the use of conditional statements to control the flow of execution based on specific conditions.

• Decision making in C programming refers to memory management techniques.

• Decision making in C programming is about defining variables.

• Decision making in C programming involves using loops for iteration.

How do branching statements work in C?

• Branching statements in C are used for memory allocation.

• Branching statements in C are only applicable in loops.

• Branching statements in C control the flow of execution based on conditions.

• Branching statements in C are used to declare variables.

Explain the different types of loops in C.

• repeat-until loop

• loop until condition met

• foreach loop

• The three types of loops in C are 'for', 'while', and 'do-while'.
