I am migrating C++ 32 bit application to 64 bit. In this to convert size_t to int I am just type casting like thisint nInLen = (int) strlen( lpstrAddrIn );Is it safe or should I declare nInLen as size_t?Please suggest anyone your ideas.Thanks....
根据下表(出自Table 2.11.1-A. Type support in the Java Virtual Machine instruction set),可以发现大部分指令都没有支持 byte、char 和 short 类型,甚至没有任何指令支持 boolean 类型。因此如果要对两个 short 类型的数字相加,那只能转成 int,再使用 iadd 命令相加,然后再转成 short 了。 基本类型有多大?
You're getting the size of the class, not of an instance of the class. Call int to get the size of an instance: >>> sys.getsizeof(int()) 24 If that size still seems a little bit large, remember that a Python int is very different from an int in (for example) c. In Python...
