my size snowman poem
What is the difference between .size() and .length ? Is .size() only for arraylists and .length only for arrays? I'm looking for detailed information regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler. But are there any standards for ... What does the C++ standard say about the size of int, long? The C standard guarantees that SIZE_MAX will be at least 65535. size_t is the type returned by sizeof operator, and is used in the standard library (for example strlen returns size_t). Denoted as Long Size = 64 bits (8byte) Can hold integers of range -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 default value is 0L If your usage of a variable falls in the 32 bit range, use `Int`, else use `long`. Usually long is used for scientific computations and stuff like that need much accuracy. (eg. value of pi).
Where do I find the definition of size_t, and what is it used for? How do I determine the size of my array in C? That is, the number of elements the array can hold?
