The main() function is used for defining global variables.

The main() function is where all the functions are declared.

The main() function handles memory allocation in a C program.

The main() function is the entry point of a C program.

A variable can change its value, while a constant cannot.

A variable is used for functions, while a constant is used for loops.

Both variables and constants can change their values.

A variable is a fixed value, while a constant can change.

integer myVariable;

var myVariable;

float myVariable;

int myVariable;

A function prototype is the actual implementation of a function.

A function prototype is a type of variable used in C programming.

A function prototype is a declaration of a function that specifies its name, return type, and parameters.

A function prototype is a comment describing a function's purpose.

function_name(parameter_name) return_type { // function body }

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

function_name(parameter_type) { // function body }

return_type function_name { // function body }

float

string

void

int

Recursion is when a function runs in parallel with another function.

Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem, requiring a base case to stop the recursion.

Recursion is a technique where a function calls another function to perform tasks.

Recursion is a method of optimizing code by removing loops.

An array in C is a collection of different types stored randomly in memory.

An array in C is a single element of any type.

An array in C is a collection of elements of the same type stored in contiguous memory locations.

An array in C is a function that returns multiple values.

Use the array subscript operator [] with the index of the element.

Use the parentheses () to index the array.

Use the dot operator . to access elements.

Access elements using the array name only.

A pointer is a type of function in C.

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

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

A pointer is a special kind of loop in C.

pointer int *ptr;

int ptr;

int *ptr;

int &ptr;

An array can change size dynamically, while a pointer cannot.

A pointer is a collection of elements, while an array is a single variable.

An array holds the address of a variable, while a pointer holds the value of an element.

An array is a fixed-size collection of elements, while a pointer is a variable that holds the address of another variable.

struct Rectangle { int length; int width; };

struct Circle { float radius; };

struct Point { int x; int y; };

struct Line { int start; int end; };

Access members using the colon operator (:).

Use the semicolon (;) for structure variables.

Use the asterisk (*) for structure pointers.

Use the dot operator (.) for structure variables and the arrow operator (->) for pointers.

To allocate memory for a variable at runtime.

To determine the size, in bytes, of a data type or variable.

To calculate the total number of variables in a program.

To convert a data type to a string representation.
