If you do not understand this then try mentally putting in if statements for the case statements. Default simply skips out of the switch case construction and allows the program to terminate naturally. If you do not like that, then you can make a loop around the whole thing to have it ...

Case2Case3Case4Default I passed a variable to switch, the value of the variable is 2 so the control jumped to the case 2, However there are no such statements in the above program which could break the flow after the execution of case 2. That’s the reason after case 2, all the su...
VBScript to combine rs values, loop and add to duplicate(s) I've written a lot of IF statements in VBScript, but haven't gone much beyond that so apologize for my lack of experience. I hope what I'm asking is simple to do. I want to output item identifiers cre... ...

意思是说,如果一个程序的执行路径从代码中的点A(某个局部变量x还未定义)跳到代码中另一点B(该局部变量x已定义,并且定义的时候有初始化),那么编译器会报错。这样的跳跃可以是由于执行goto语句,或者是switch-case造成的。 这里有两种情况:首先,对于POD对象而言,只有当有初始化式的声明被跳过时才会报错。
