switch “transfer of control bypasses initialization of:” when calling a function

Question

I get a \"transfer of control bypasses initialization of:\" error when i try to build the following switch:

switch (retrycancel)
{
    case 4:    //The user          


        

Answer 1

a switch is essentially a goto, that is, it is a goto to the appropriate label. The C++ standard forbids a goto to bypass an initialization of a non-POD object. Take the vector declaration into braces and it will solve the problem

switch (retrycancel)
    {
     case 4:                //The user pressed RETRY
     {
        std::vector windows = MainHandles().enum_windows().get_results(); //Enumerate all visible windows and store handle and caption in "windows"
        break;
     }
    case 2: 
        //code
    }
