Reposted from Sina Blog: 1: Why not use the GOTO statement? Source (from Wikipedia ): Goto is a statement that can be found in many computer programming languages. It is an English word.GoAndTo. When executing this statement, it transfers the

Objective A goto statement is also called an unconditional transfer statement, and its basic form is as follows: Statement marking by a valid identifier and symbol ";" , where the identifier's naming convention is the same as the variable name,

Dome # Include # include int main () {int n = 7; number2: printf ("Hello world \ n"); If (n = 7) {n = 8; printf ("n = 7 start \ n"); goto number0; printf ("n = 7 end \ n ");} else {printf ("n = 8 start \ n"); goto number1; printf ("n = 8 end \ n")

　　Function: the reuse of code can be Implemented.       function only needs to be defined 1 times, then the code in the function can be arbitrarily called. -the Basic concept of an unknown source　　Learning and time learning, such as the wrong pen,

Goto can only jump to the function body, but not to the function in vitro. That is, Goto has a local scope and needs to be in the same stack. To jumpProgramSegment start point plus the label. Part2 in the following example. 1. The GOTO statement

When considering what C + + is doing, Java is doing a good deed, simplifying the issue of how parameters are passed. In C + +, there is no method in C + +, which should be called "function" or "member function", and the parameters and method calls

Use inline assembly in Visual C ++    I. Advantages  Inline assembly can be used to embed assembly language instructions in C/C ++ code without additional assembly and connection steps. In Visual C ++, inline assembly is a built-in compiler, so you
