2、int、unsigned int 、short int、unsigned short 、long int 、unsigned long、float、double、long double类型的sizeof 在ANSI C中没有具体规定,大小依赖于实现,一般可能分别为2、2、2、2、4、4、4、8、10。 3、当操作数是指针时,sizeof依赖于编译器。例如Microsoft C/C++7.0中,near类指针字节数为2,far...

Java supports eight basic primitive data types. This tutorial explains basic primitive data types (int, long, short, byte, char, boolean, float, double) with their size, range and default value. Java basic data types are predefined and implicit to the la
