What is the syntax for declaring an array in C?

• array_name = [array_size];

• array_name = data_type[array_size];

• array_name[array_size] = data_type;

• data_type array_name[array_size];

What is the syntax for declaring a pointer in C?

• int ptr;

• ptr = int;

• int *ptr();

• int *ptr;

How is pointer arithmetic performed in C?

• By dividing the pointer by an integer value

• By multiplying the pointer with an integer value

• By adding or subtracting an integer value to/from a pointer

• By performing bitwise operations on the pointer

What is the difference between array and pointer in C?

• Arrays are a fixed-size collection of elements, while pointers are variables that store memory addresses.

• Arrays cannot be passed as arguments to functions, while pointers can

• Arrays can only store integers, while pointers can store any data type

• Arrays and pointers are the same thing

Explain the concept of passing an array to a function in C.

• Passing an array to a function in C only allows access to the first element of the array

• Passing an array to a function in C allows the function to work with the elements of the array.

• Passing an array to a function in C is not possible

• Passing an array to a function in C allows the function to modify the size of the array

How can you dynamically allocate memory for an array using pointers in C?

• Use the 'realloc' function

• Use the 'malloc' function

• Use the 'free' function

• Use the 'calloc' function

What is the purpose of the 'const' keyword in C?

• To declare a constant variable that cannot be modified

• To declare a variable that can only be modified within a specific function

• To declare a variable that can be modified by any function

• To declare a variable that can be modified by any other variable

Explain the concept of dynamic memory allocation in C.

• Dynamic memory allocation in C allows the program to allocate memory at compile time

• Dynamic memory allocation in C allows the program to allocate memory at runtime

• Dynamic memory allocation in C is not possible

• Dynamic memory allocation in C allows the program to allocate memory for global variables only

What is the purpose of the 'static' keyword in C?

• To declare a variable that can be accessed only within the same function

• To declare a variable that retains its value between function calls

• To declare a variable that can be modified by any other variable

• To declare a variable that can only be modified within a specific function

What is the syntax for declaring a multi-dimensional array in C?

• data_type array_name[array_size1][array_size2];

• array_name = data_type[array_size1][array_size2];

• array_name = [array_size1][array_size2];

• data_type[array_size1][array_size2] array_name;
