c++ - Error: Jump to case label in switch statement The problem is that variables declared in one case are still visible in the subsequent cases unless an explicit { } block is used, but they will not be initialized because the initialization code belongs to another case.. In the following code, if foo equals 1, everything is ok, but if it equals 2, we'll accidentally use the i variable which does exist but probably contains garbage.

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.

Error - crosses initialization? - C++ Forum - cplusplus.com In C/C++, switch statements allows fall-through semantics with the case labels.

Declaring Variables in Switch Statements - Faye Williams error: jump to case label error: crosses initialization of 'int x' "Huh?" You say, peering at the computer screen. Your code looks fine, so what does it mean? Look closely at your switch statement. A switch statement contains case labels, which provide options to do different things after checking the value of a variable.

This is useful when one structure, such as the skull, obstructs the view of another. Visibility: A label can be hidden from display, either in the 3D window or in all windows. Like transparency, this can be used to hide obstructing structures.

31 Error Jump To Case Label - Labels Database 2020

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.
