//Scope enumeration #includeusing namespace std;/* There are two ways to define enumerations with errors, The error hint is the enumerator sum redefined. Before c++11 we cannot define two enum types in a class with the same enumerator. This causes

The rand () function obtains a random number by calculating a value from a variable called a "seed", and then the resulting value is then used as the new "seed" to participate in the next operation, thus obtaining the so-called random numberThe role

Many novice programmers often make a mistake, that is, I = 3, and i = = 3 are confused with each other, the former represents an assignment statement, and the latter is often used as a condition of judgment. Some programmers want to point the

Do not neglect the compiler's warningsCompiler warnings don't bother some programmers. They believe that warnings do not threaten the program or do not have much of a side effect on the program. However, this idea may cost a great price when it

There is nothing to say, just a test to see why there are some inexplicable rules. I used to learn C + + When I did not understand these things, I hope for some people still helpful ~ ~The following source code is passed under vc++6.0.tab becomes

Writing multithreaded related programs in Java is a lot simpler, and when you need to synchronize in multiple threads, you can use synchronized.Recently learning C multi-threading and synchronization, feel implemented, to write more code, this may

You need to stick to the routine when writing new and deleteThis section describes what requirements should be adhered to when customizing the new and delete functions, and why these requirements are adhered to.first, as described in the following

Constants and pointersVariables that can be modified after a declaration are declared as constants if they cannot be modified in order to protect the variable, using the const modifier.In C + +, a pointer variable is assigned a 4-byte (32-bit) block

A static constructor is a new feature of C #, which seems to be seldom used. But we need to use it when we want to initialize some static variables. This constructor belongs to the class, not to the instance where it belongs, meaning that the

The Intermediate code (IL) is an internal representation of the source program for example C language compiling a program then C language compilationThe Translator will translate all the code into machine instructions that can be machine-recognized.
