Q2. Name the storage classes and explain the uses
Ans. 
Storage classes in C are auto, register, static, and extern. They control the scope and lifetime of variables.
• Auto - default storage class for local variables, stored in stack memory

• Register - stored in CPU registers for faster access

• Static - retains its value between function calls, stored in data segment

• Extern - used to access global variables across multiple files
