The switch expression must evaluate to an integer or a value that can be promoted to an integer type

If no break statement is used after a case, execution continues into the next case, if present

The default case is optional in a switch statement

The switch expression can be of any data type, including float and double

Two case labels in the same switch can have the same constant value

They can be accessed from other files using extern

They can be used in any function in the same file

They are destroyed when a function ends

They are stored in the heap

They are created once when the program starts

They are stored in the stack memory

int arr[3] = {1, 2, 3};

int arr[3] = {1, 2, 3};

int arr[3] = {1, 2, 3};

int arr[3] = {1, 2, 3};

The result of a logical operation is always either 0 or 1

Logical operators in C include &&, ||, and !

Logical operators perform bit-level operations on integer operands

The expression (a && b) returns true only if both a and b are nonzero

The logical AND operator is &, and the logical OR operator is |

It automatically sets the pointer to NULL after freeing

It releases memory allocated by malloc()

It is the programmer’s responsibility to call it

It accepts a pointer previously returned by an allocation function

It cannot be simulated by realloc()

All function parameters should have the same type

They exist only while the function is running

They are not accessible when the function ends

They are stored in the stack memory

They can be accessed from other functions using extern
