Regression test cases are also based on the requirement documents. They are written more into detail and with every release (build), the testers need to do regression testing. The criteria for regression testing are; there should be no major defects while we do our smoke test and functional testing.

ARC is a compiler-level feature that simplifies the process of managing the lifetimes of Objective-C objects. Instead of you having to remember when to retain or release an object, ARC evaluates the lifetime requirements of your objects and automatically inserts the appropriate method calls at compile time.

In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband

transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

i.) Const - This variable means that if the memory is initialised once, it should not be altered by a program. 

ii.) Volatile - This variable means that the value in the memory location can be altered even though nothing in the program code modifies the contents. 

iii.) Mutable - This variable means that a particular member of a structure or class can be altered even if a particular structure variable, class, or class member function is constant.

In C++, void represents the absence of type, so void pointers are pointers that point to a value that has no type. The void pointers can point to any data type.

You can declare void pointer as follows:

void *p;

The finalize method is called by the garbage collector, just before releasing the object’s memory. It is normally advised to release resources held by the object inside the finalize method.
