Q1. Can you provide an example of how to use pointers in C/C++ and discuss different concepts related to them?
Ans. 
Pointers in C/C++ are variables that store memory addresses. They are used to manipulate memory directly and improve performance.
• Pointers are declared using an asterisk (*) before the variable name.

• Pointers can be used to dynamically allocate memory using functions like malloc() and free().

• Pointers can be used to pass variables by reference to functions.
