Q1. What is the smart pointers?
Ans. 
Smart pointers are objects that store a pointer to dynamically allocated memory and provide automatic memory management.
• Smart pointers help prevent memory leaks by automatically releasing memory when the pointer is no longer needed.

• Examples include unique_ptr, shared_ptr, and weak_ptr in C++.

• unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to break circular references.

Q2. What is the lamda function?
Ans. 
A lambda function is a small anonymous function defined in a single line of code without a name.
• Lambda functions are often used in programming languages that support functional programming.

• They are commonly used for short, simple operations that do not require a named function.

• Lambda functions can take any number of arguments but can only have one expression.

• Example: lambda x: x*2 defines a lambda function that doubles
