Learn and Master C Programming - A r Look At How Pointers Work!

The video tutorial recaps previous lectures on using pointers with variables, focusing on memory allocation for integers and pointers. It explains the differences in pointer size between 32-bit and 64-bit systems and demonstrates how to assign pointers to variables and memory addresses. The tutorial also covers indirect memory access by modifying values through pointers, providing a comprehensive overview of the topic.

What is the memory size occupied by an integer variable in a typical program?

• 16 bytes

• 8 bytes

• 4 bytes

• 2 bytes

In a 32-bit program, how many bytes does a pointer use to store a memory address?

• 2 bytes

• 8 bytes

• 4 bytes

• 6 bytes

How many bytes does a pointer use to store a memory address in a 64-bit program?

• 2 bytes

• 4 bytes

• 6 bytes

• 8 bytes

What happens when you assign a value to the contents of a pointer?

• The pointer itself changes its address

• The value at the memory address the pointer points to is modified

• The pointer is deleted

• The program crashes

What is the role of a pointer in relation to a variable?

• It stores the variable's value directly

• It holds the memory address of the variable

• It increases the variable's size

• It decreases the variable's size
