If you have some understanding of XML format files, you should know that it is a very common format used for storing and transmitting data, such as configuration files and data exchange. <strong>TinyXML</strong> is a lightweight library specifically designed for … Read more
1. Introduction This article will focus on the usage of system-defined Find modules and how to write your own Find modules. The system provides various other modules, which generally need to be explicitly called using the INCLUDE directive. The FIND_PACKAGE directive is a special case that can directly invoke predefined modules. In fact, managing a … Read more
Namespaces in C++ are used to organize an excessive number of classes for easier handling of applications. To access classes within a namespace, we need to use namespacename::classname. We can also use the using keyword, so we don’t have to keep using the full name. In C++, the global namespace is the root namespace. global::std … Read more
Standard header files include: <asset.h> <ctype.h> <errno.h> <float.h> <limits.h> <locale.h> <math.h> <setjmp.h> <signal.h> <stdarg.h> <stddef.h> <stdlib.h><stdio.h> <string.h> <time.h> 1. Standard Definitions (<stddef.h>) The file <stddef.h> contains some common definitions of the standard library, and it is automatically included whenever any standard header file is included. This file defines: Type size_t (the result type of the … Read more
