Nov 25, 2013 · What is the difference between .size() and .length ? Is .size() only for arraylists and .length only for arrays?

If the size of the int is that important one can use int16_t, int32_t and int64_t (need the iostream include for that if I remember correctly). What's nice about this that int64_t should not have issues on a 32bit …

Aug 28, 2019 · I found two ways to determine how many elements are in a variable… I always get the same values for len () and size (). Is there a difference? Could size () have come with an imported …

I'm really curious why shape is an attribute of arrays and a function in the numpy model but not a method of array objects. Is there an obvious answer? Does it feel like it merits a separate SO …

I am working with code that uses types like uint8 (1 byte wide unsigned integer), uint16 (2 byte wide unsigned integer), uint32 (4 byte wide unsigned integer), etc.. My questions are: Are uint8 an...

In several C++ examples I see a use of the type size_t where I would have used a simple int. What's the difference, and why size_t should be better?

May 2, 2011 · 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 …

So, the size of size_t is not specified, only that it has to be an unsigned integer type. However, an interesting specification can be found in chapter 7.18.3 of the standard: limit of size_t SIZE_MAX …

Closed 3 years ago. Is the size of a pointer the same as the size as the type it's pointing to, or do pointers always have a fixed size? For example...

Dec 23, 2009 · 82 size_t is the result type of the sizeof operator. Use size_t for variables that model size or index in an array. size_t conveys semantics: you immediately know it represents a size in bytes or …
