"long int", and "long long int". In this list, each type provides at least as much storage as those preceding it in the list. Plain ints have the natural size suggested by the architecture of the execution environment (44); the other signed integer types are provided to meet special n...
而在C/C++中需要sizeof是因为移植,不同的数据类型在不同的机器上大小可能不同,程序员必须知道对应的数据类型大小。 详细介绍 Java数据类型 Java基本数据类型 int 32bit short 16bit long 64bit byte 8bit char 16bit float 32bit double 64bit boolean 1bit Java基本数据类型封装类 Integer // 4 byte Short ...
I have the following code. The output for the first 2 is 4. The output for the last is 8. Why is a long integer the same size of a normal int (4 bytes)? I am running a PC with 64-bit Windows 10 OS. 1 2 3 4 5 6
