The vector contains is a method/function in C++ that returns a boolean value indicating whether a vector contains a specific element or not. The method searches for the provided element in the vector and returns true if it is found, false if not.

Example 1: Checking if a vector of integers contains a specific number

#include 
#include 

int main() {
    std::vector nums = {1, 2, 3, 4, 5};
    int num_to_check = 3;

    if (std::find(nums.begin(), nums.end(), num_to_check) != nums.end()) {
       std::cout << "The vector contains " << num_to_check << std::endl;
    } else {
       std::cout << "The vector does not contain " << num_to_check << std::endl;
    }
    return 0;
}

Example 2: Checking if a vector of strings contains a specific word

#include 
#include 
#include 

int main() {
    std::vector words = {"hello", "world", "foo", "bar"};
    std::string word_to_check = "baz";

    if (std::find(words.begin(), words.end(), word_to_check) != words.end()) {
       std::cout << "The vector contains " << word_to_check << std::endl;
    } else {
       std::cout << "The vector does not contain " << word_to_check << std::endl;
    }
    return 0;
}

These examples use the standard library functions `std::find()` and `std::vector`. Therefore, the package/library used is the Standard Template Library (STL), which is part of the C++ standard.
