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?
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 library (like...
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).
From the friendly Wikipedia: The stdlib.h and stddef.h header files define a datatype called size_t which is used to represent the size of an object. Library functions that take sizes expect them to be of type size_t, and the sizeof operator evaluates to size_t. The actual type of size_t is platform-dependent; a common mistake is to assume size_t is the same as unsigned int, which can lead to ...
In C, the type of a character constant like 'a' is actually an int, with size of 4 (or some other implementation-dependent value). In C++, the type is char, with size of 1. This is one of many small differences between the two languages.
Why is the size of a character sizeof('a') different in C and C++?
