41 jump to label crosses initialization

Apple - Lists.apple.com Yes, anytime you use goto to jump into the lifetime of an automatic variable. That is, you jump to a point after the object is initialized, but before it is goes out of scope, thereby not allowing the constructor to be called (or in this case, the reference to be initialized), you've invoked undefined behavior. > How can I fix it? C Language, "jump in case label" - Index page test.cc:9: crosses initialization of `int x' The ``jump to case label'' is not a complete message; it is the start of a sentence continued on the second line: ``jump to case

Jump to case label - Programming Questions - Arduino Forum So it's saying that you jump across the initialization of several variables. That means that they are still in scope, but they haven't been initialized. So you can either put a pair of braces around the cases that initialize variables (thereby creating a new scope) or initialize the variables before the switch statement.

#defined names of switch (error: jump to case label ) - Arduino Forum It's saying that the jump to "case 2:" on line 27 (the '2' being the expansion of the macro 'WRITE' declared on line 10) jumps past the initialization of the local variable 'out' declared on line 14. If that jump were allowed then the local variable would be 'in scope' (visible) but not initialized. 【C++ 异常】error: jump to case label [-fpermissive] - 简书 blue_smile关注. 编译程序时，编译器报错 error: jump to case label [-fpermissive] ， error: crosses initialization of 'xxxx' ，对相关内容进行简单的梳理. 从上面的代码中可以看出，因为switch中没有单独的区域块来限定变量i的声明周期，所以变量的作用域是初始化点到switch的结尾 ... How do I resolve this error: jump to case label crosses initialization A "case" of a switch doesn't create a scope, so, as the error says, you're jumping over the initialization of "sum" if the choice isn't 1. You either need to declare sum and diff outside the switch, or create blocks with { } for each of the cases.

JaWiB. View Profile View Forum Posts carry on Join Date Feb 2003 ... Why I can't declare a std::string type in a switch/case box? A switch case is the same as a labeled "goto" statement. You are not allowed to "goto" a location in a block following the construction point of a local variable, and you can't do it with a switch either. The problem is, the string is still in scope at case 2. Each labeled section of a switch statement is NOT its own scope. 28031 - [4.2 regression] bogus jump to case label crosses ... The reason is that if the value of "i" is 1, you will end up in the "case 1" part with "j" uninitialized. You can put the entire body of the outer "case 0" inside braces, so that "j" is not in scope in the "case 1" part; that will eliminate the error.

Crosses initialization of string and jump to label case case labels are really a lot like dreaded goto labels; they do not constitute a new scope. Consequently, a switch selecting the correct case label to jump to is, for better or worse, a lot like goto statement jumping to a label. The jump is not allowed to cross the initialisation of your various objects - exactly as the error messages say.
