Libraries involved in Windows programming
Explain the important libraries involved in Windows programming?
Expert
There libraries which are used in Win32API are as follows:
a. MSVCRT.DLL: It is used as a dynamic link library or DLL which consists of the application logics.
b. The application of the standard library (stdlib) as well as its purposes is selected for Windows programming environment.
c. The functions that are used get defined in the common header files stdio.h, string.h, stdlib.h, and additional library files which are associated with it.
d. WS2_32.DLL: It provides Winsock2 library that contains the standard socket API which can be used to communicate on the internet.
Untyped Allocations: In C/C++ untyped allocations such as malloc, calloc, and realloc can easily be used to create overlays, which again require translation overhead to keep the corresponding non-overlaid objects consistent. Q : Define the term Address space Define Define the term Address space: The region of virtual memory in which a procedure is run.
Define the term Address space: The region of virtual memory in which a procedure is run.
Illustrate the difference between the choice and list?
Unchecked exception: An exception for which it is not needed to give a local try statement or to propagate through a throws clause stated in the method header. An exception which is not handled will cause program annihilation when it is thrown.
Assembly language: This is a symbolic language closely analogous to the instruction set of a Central Processing Unit. The program employed to translate a program written in assembly language is termed an assembler.
Explain Downcast with example: It is a cast towards an object's dynamic kind - that is, `down' the inheritance hierarchy. For illustration: // Downcast from Object to String
Memory leak: It is a situation in which memory which is no longer being employed has not been returned to the pool of free memory. The garbage collector is designed to return unreferenced objects to the free memory pool in order to shun memory leaks.<
Byte: In general computing, it refers to eight bits of data. In Java it is as well the name of one of the primitive data types, whose size is of eight bits.
What is Modal: A dialog is a modal when its parent application is blocked from additional activity until the dialog has finished.
Object construction: The creation of an object, generally through the new operator. Whenever an object is formed, a suitable constructor from its class is summoned.
