Which of the following is true about pointer arithmetic in C++?a)It is...
Pointer arithmetic is allowed in C++ for pointers of any type. When performing pointer arithmetic, the size of the data type being pointed to is taken into account. For example, adding 1 to an 'int*' pointer moves the pointer by the size of an integer.

Pointer Arithmetic in C++
Pointer arithmetic is a feature in C++ that allows operations to be performed on pointers. It is a powerful tool that is widely used in programming.
Allowed for Pointers of Any Type
In C++, pointer arithmetic is allowed for pointers of any type, not just for built-in types. This means that you can perform arithmetic operations such as addition, subtraction, increment, and decrement on pointers that are pointing to any type of data.
Example
For example, if you have a pointer pointing to an integer array, you can use pointer arithmetic to access and manipulate the elements of the array. You can also use pointer arithmetic to iterate through arrays, strings, and other data structures.
Use Cases
Pointer arithmetic is commonly used in scenarios where direct memory manipulation is required, such as in low-level programming, data structures, and algorithms. It allows for efficient and concise code that can be optimized for performance.
Conclusion
In conclusion, pointer arithmetic is a powerful feature in C++ that is allowed for pointers of any type. It provides flexibility and efficiency in programming, making it a valuable tool for developers.
