C++

The memory used by a program compiled by C + + is divided into the following sections1. Stack (stack)-the program is automatically assigned by the compiler when it is run, storing the parameter value of the function, the value of the local variable,

#include #define M 10int my_atoi (char s[]) {int num=0;     int i=0;           while ((S[i]=getchar ()) = ' \ n ') {if (s[i]>= ' 0 ' &&s[i] C language Implementation, converting a string to the corresponding integer

polymorphicPolymorphism refers to the use of the same function name to access the different implementation methods of the function, can be summarized as "one interface, many methods."C + + supports compile-time polymorphism (also called static

C Language 32 Keywords First Category: Data type keywords A basic data type (5) void Declares that a function has no return value or no parameter, declares an untyped pointer, and explicitly discards the result of the

Global variables are stored in the same way as static variables, except in different scopes. If they are not initialized or initialized to 0, they are stored in the BSS segment, and if initialized to a value other than 0 is stored in the data

Reflection Definition: the ability to review metadata and collect type information about it. Metadata (the most basic data unit after compilation) is a whole bunch of tables, and when the assembly or module is compiled, the compiler creates a class

This is a list of questions I has gathered from the other sources and created myself over a period of time from my experience  , many of which I felt where incomplete or simply wrong.  I have a finally taken the time to go through each question and
