Sort (C++) - Usage

Usage

The sort function is included from the algorithm header of the C++ Standard Library, and carries three arguments: RandomAccessIterator first, RandomAccessIterator last, Compare comp. The third argument has default value - the "less-than" (<) operator to compare elements.

This code sample sorts a given array of integers (in ascending order) and prints it out. Pointers into the array serve as iterators.

#include #include int main { int array = { 23, 5, -10, 0, 0, 321, 1, 2, 99, 30 }; int elements = sizeof(array) / sizeof(array); std::sort(array, array + elements); for (int i = 0; i < elements; ++i) std::cout << array << ' '; }

The same functionality using vector container:

#include #include #include int main { std::vector vec; vec.push_back(10); vec.push_back(5); vec.push_back(100); std::sort(vec.begin, vec.end); for (int i = 0; i < vec.size; ++i) std::cout << vec << ' '; }

Famous quotes containing the word usage:

“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)

“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)

“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
