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. 15 to change the size of (almost) all text elements, in one place, and synchronously, rel() is quite efficient G+theme(text = element_text(size=rel(3.5)) you might want to tweak the number a bit, to get the optimum result It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. It is unlikely that any implementation will use wider type for ssize_t than it uses for size_t
This immediately means that the price you will pay for the ability to return negative values is halving of the positive range of the type Ssize_max is usually size_max / 2 This should be kept in mind. I have inherited a fairly large sql server database It seems to take up more space than i would expect, given the data it contains Is there an easy way to determine how much space on disk each t.
What's the difference, and why size_t should be better? What is the command to find the size of all the databases I am able to find the size of a specific database by using following command The size_t type is the unsigned integer type that is the result of the sizeof operator (and the offsetof operator), so it is guaranteed to be big enough to contain the size of the biggest object your system can handle (e.g., a static array of 8gb) The size_t type may be bigger than, equal to, or smaller than an unsigned int, and your compiler might make assumptions about it for optimization. 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. The approach basically builds on other work where people experimentally identified the size of primitives and typical java objects and then apply that knowledge to a method that recursively walks an object graph to tally the total size. 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). My absolute largest repository contains only images of various formats, it's an artwork repo of icons which i use in various apps Yet, github reports the size as 0
