In the first section of chapter II, "C pitfalls and defects", there is such a declaration:(* (Void (*) ()) 0) ()；Seeing this expression estimate makes a lot of people "shudder", in fact, although it seems complicated, but constructs such expression

1. The function body is the computer instruction of what the function should do.2. In the C language, each complete instruction becomes a statement.3. The statement ends with a semicolon, and you should not omit the semicolon when you enter the code.

Both string and string exist in C #Description of string in MSDN:string is a alias for string in the. NET Framework. String is a string alias, string is a class in C #, string is the class of the framework, and C # string is mapped to a string of

The previous article wrote that I didn't get the data by parsing the HTML, but by parsing the request link and then simulating the request method to get the data, which is just one way. And in the case that I can't get through the analysis of HTML,

Use SendKeys to send keystrokes and combo keystrokes to the active application. This class cannot be instantiated. To send a keystroke to a class and resume the program flow immediately, use send. To wait for any process that is started by the

1. Abnormal captureWe often have a variety of anomalies in the program, if you want your program to become stronger.You should use Try-catch frequently for exception trapping in your code.Which line of code is likely to be abnormal, you kick it one

Heard someone say that there is no pointer in C #, so want to write a C # in the use of pointers;C # Pointers are unsafe code, that is, the pointer runs under unmanaged code.And there is a certain difference in the definition of pointers in C # and

1, in the main () function, we call the test () function, we call the main () function called the caller,The tube test () function is called the callee.If the callee wants to get the caller's value:1), passing parameters.2), use static fields to

A pointer to a function函数名可以在表达式中被解读成“指向函数的指针”, so, as in the experiment in Listing 2-2, a pointer to a function can be obtained as a func.A pointer to a function is essentially a pointer (address), so you can assign it to a pointer-type

Const-modified constants cannot be directly modified, but can be indirectly modified through pointers.In the following code, const-qualified a cannot be directly modified. Void main () {const int a = 3; a = 1 ;} In C ++Const-modified constants
