Char *ptr; // then omit part of the code if ((int) ptr==-1 ) // wrong Place The meaning of the sentence is from void* to int conversion loss Precision, I believe see explanation some people understand,This problem only occurs on Linux with the X64 bit, because the pointer occupies 8 bytes on a 64-bit machine, and int occupies four bytes, so this problem occurs.Workaround:(long) ptr = =-1 just fine.About Linux under C compile error (warning) cast

Use the code on StackOverflow to describe the problem: Objectmapper mapper = new Objectmapper (); listThe conversion will not have an error, but it will throw an exception when getting the specific data:System.out.println (list.get (0)); System.out.println (List.get (0). Getforename ()); return list;There is very little exception information.Workaround:listJackson conversion Generic list error java.util.LinkedHashMap cannot be cast to com.xxx

A type conversion operator is a special class member function that defines a transformation that converts a class type value to another type value. The conversion operator is declared in the class definition body, followed by the target type of the transformation after the reserved character operator. A conversion function is also called a type cast member function, which is a non-static member function in a class. It is defined in the following forma

The role of "styling" (Cast) is to "match a model". When appropriate, Java converts one data type automatically to another. For example, suppose we assign an integer value to a floating-point variable, and the computer automatically converts the int to float. By styling, we can explicitly set this type of conversion, or force it to proceed when it is not normally possible.To make a styling, place the desired data type (including all modifiers) in pare

Label:In SQL Server, both the cast and CONVERT functions are available for type conversions, and their functions are the same. It's just a different syntax.

In stored procedures or other situations, we often need to convert data from datetime type to varchar type; convert and cast can be used in this case.Because SQL Server provides two functions, it is easy to confuse which function should be selected or under which situation this function should be used.
