  Static For all objects of a specific class type, it is sometimes necessary to access a global object. However, for a class, global objects may destroy encapsulation. Instead, the class defines static members to replace a universally accessible

Example: Typedef Enum {encoding, gb2312_encoding_type, hkscs_encoding_type, no_of_text_encoding,} textencodingenum; const kal_uint8 * encoding [no_of_text_encoding]; As shown in the preceding example, no_of_text_encoding is the number of valid

References are a concept in C ++. Beginners can easily confuse references with pointers.In the following program, n is a reference of M, and M is a referent ).Int m;Int & n = m;N is equivalent to M alias (nickname). Any operation on N is an

GCC is the most widely used tool for compiling C and C ++ languages in Linux. Unlike C and Java, generating an executable file is divided into two parts: Compilation and connection. Let's take a brief look. For example, to compile a Test. c

In C and C ++ languages, memory leakage is very likely due to the great flexibility of memory operations. Fortunately, we have a third-party memory leak check tool, which is the PurifyPlus of Rational (Now IBM. Purify on Windows may be widely used,
