javascript goto

Today, someone asked me if there is any goto in Java. When I read his questions, I knew that he was learning C. Well, I didn't really pay too much attention to this problem before, because I know that GOTO is a keyword in Java, but it seems that it has never been used, he asked me again, if you want to jump out of a few loops, how to operate? I still have a way to solve this problem ...... Public class te

---- Start Anyone who has learned any programming language is familiar with continue and break. In SQL PL, iterate and leave play the same role. Return serves the same purpose as most programming languages and is used to return the results to the caller. In addition, the GOTO statement is also supported in SQL pl. It is generally not recommended to use goto because it will confuse the program. I. Syntax Ite

The difference between Go's If,for,switch and C People who have a C foundation know that if, for, and switch conditional languages are bracketed.

The syntax rules are as follows: if 语句 {}for 语句1;语句2;语句3 {}//跟C一样，这三个语句可以省掉任何一个语句switch 语句 {} The difference

A tag is usually placed at the end of a function and will be executed. In many cases, the tag is executed in the order from top to bottom. Goto allowsCodeAutomatically jump to the Code defined by the tag to continue execution. # Include Int main (){Int I, J;For (I = 0; I {Printf ("outer loop executing. I = % d \ n", I );For (j = 0; j {Printf ("inner loop executing. j = % d \ n", J );If (I = 15) // although this condition is not trueGoto stop;}}/

Use goto elegance and avoid structural confusionThe statement you want to jump to with do{...} while (0) you can wrap it up.Reference #defien N BOOLExecute () {//Allocate resources int*p = (int*)mallocNsizeof(int));BOOLBOk =true;//Run and error handlingBOk = Func1 ();if(!bok) { Free(p); p = NULL;return false; } bOk = Func2 ();if(!bok) { Free(p); p = NULL;return false; } bOk = Func3 ();if(!bok) { Free(p); p = NULL;return false; }// .......... //R

are as follows: If there is a valueof () method, call the ValueOf () method. If this method returns a literal, it is converted to a numeric return. If there is no valueof () method, or there is no return literal, and the ToString () method is called, the ToString () method of the object is invoked, and if a literal is returned, the literal is converted to a number and returned. The literal turn figures are shown in the table above. If neither of these steps succeeds, a type err

)Comparisons of suffix (3*i+1) and suffix (3*j+2) can be obtained quickly using the results of (2). The second case is the comparison of suffix (3*i) and suffix (3*j+2), which can be expressed as suffix (3*i) and suffix (3*j+2):Suffix (3*i) = R[3*i] + r[3*i+1] + suffix (3*i+2)Suffix (3*j+2) = r[3*j+2] + r[3*j+3] + suffix (* * (j+1) +1)By the same token, comparisons of suffix (3*i+2) and suffix (j+1) +1 can be obtained quickly using the results of (2). So each time the comparison can be done effi
