C Programming Fundamentals Assessment

What are the basic data types in C?

• int, float, double, char, void

• boolean

• array

• string

How do you declare a variable in C?

• var variableName;

• float variableName;

• int variableName;

• string variableName;

What is the purpose of the 'if' statement?

• To declare a function in the code.

• To create a loop for repeated execution.

• To control the flow of execution based on a condition.

• To define a variable in a program.

Explain the use of 'for' loops in C.

• 'for' loops in C do not require a condition to terminate.

• 'for' loops in C can only iterate over arrays.

• 'for' loops in C are used for repeated execution of code with a defined number of iterations, structured

• 'for' loops in C are used for error handling in programs.

What is recursion in programming?

• Recursion is a method where a function solves a problem by calling itself.

• Recursion is a process of optimizing code by removing loops.

• Recursion is a method where a function runs in parallel with another function.

• Recursion is a technique where a function is executed only once.

How do you define a function in C?

• return_type { function_name(parameter_type) }

• return_type function_name(parameter_type parameter_name) { // function body }

• function_name(parameter_type) return_type { // body }

• function_name { return_type parameter_type; }

What is a pointer in C?

• A pointer is a type of function in C.

• A pointer is a variable that stores a string in C.

• A pointer is a variable that holds the address of another variable in C.

• A pointer is a special kind of loop in C.

How do you allocate memory dynamically in C?

• Use 'sizeof' to allocate memory dynamically

• Use 'printf' to allocate memory

• Use 'malloc', 'calloc', or 'realloc' functions to allocate memory dynamically in C.

• Use 'free' to allocate memory

What is the difference between an array and a string in C?

• A string is a fixed-size data structure, while an array can change size dynamically.

• An array can only store integers, while a string can store any data type.

• An array is always one-dimensional, while a string can be multi-dimensional.

• An array is a collection of elements of the same type, while a string is a character array terminated by a null character.

How do you access elements in an array?

• Use array[index] to access elements.

• Elements can be accessed using array->index.

• Access elements by calling array[index].get() method.

• Use array.get(index) to access elements.
