1. Tools for writing Programs:The indent command automatically adjusts the indentation style of the C code, and the individual prefers INDENT-KR2. Compile the C language program:1.GCC Compiler:GCC is an ANSI C-compatible compiler, and the C + +

2. The struct has its own meaning in C, and although it is extended to a class in C + +, the general situation follows the usage in C3.c++ general use class to make a keyword declaration4. Inheritance is the way code is reused in C + +, and through

One character set and ASCII codeConclusion: A character is essentially an integer, and each character has a unique integer corresponding to it.For example, the lowercase a corresponds to the 97,b corresponding to the 98,c corresponding to 99, the

1. Sealed keywordWhen the sealed modifier is applied to a class, this modifier prevents other classes from inheriting from the class. Similar to the final keyword in java.In the following example, Class B inherits from class A, but no class can

FunctionA larger program should generally be divided into a number of blocks, each of which is used to implement a specific function. All high-level languages have the concept of subroutines, which implements the function of modules with subroutines.

In general, all lines in the source program are Compiled. however, Sometimes it is desirable to compile a part of the content only if certain conditions are met, that is, to specify the conditions for the compilation of some content, which is
