Vector

Vector

Template arguments

T - Type of elements.

Functions

push_back

Return: none
Arguments: T

Adds an element to the back.

operator[]

Return: T
Arguments: unsigned int

Access specified element.

size

Return: unsigned int
Arguments: none

Returns the number of elements.

empty

Return: bool
Arguments: none

Returns whether the vector is empty.

begin

Return: iterator
Arguments: none

Returns an iterator to the begining.

end

Return: iterator
Arguments: none

Returns an iterator to the end.

Usage

Library include

#include "path/to/Basic-Data-Structures/include/vector"

Vector declaration

Vector<int> v;

Basic push_back and operator[] usage

v.push_back(3);  // vector: 3
v.push_back(7);  // vector: 3 7
v.push_back(-2); // vector: 3 7 -2
v[1] = 4;        // vector: 3 4 -2
std::cout << v[2] << "\n"; // prints -2
std::cout << v[1] << "\n"; // prints 4

Print vector using size and operator[]

for(int i = 0; i < v.size(); i++) {
    std::cout << v[i] << "\n";
}

Print vector using iterator with range-based for loop and auto (C++11)

for(auto i : v) {
    std::cout << i << "\n";
}
