What Size Battery For A 2007 Bmw 328i

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 system (this will impact the performance though).

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...

In this case, depending upon what your use case is, you might be better off using int (or long long) for s1 and s2. There are some functions in C/POSIX that could/should use size_t, but don't because of historical reasons. For example, the second parameter to fgets should ideally be size_t, but is int.

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.
