- Difference between size and length methods? - Stack Overflow
What is the difference between size() and length ? Is size() only for arraylists and length only for arrays?
- What does the C++ standard say about the size of int, long?
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)

- Whats sizeof(size_t) on 32-bit vs the various 64-bit data models?
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 65535 Which basically means that, irrespective of the size of size_t, the allowed value range is from 0-65535, the rest is implementation dependent

- Initializing the size of a C++ vector - Stack Overflow
1 You initialize the size when you have a good idea of the number of elements that you need to store in the vector If you are retrieving data from database or other source for instance that you know has 1000 elements in it then it makes sense to go ahead and allocate the vector with an internal array that will hold that much data
