How can I search for STL vectors in C++?

How can I search for STL vectors in C++?

You can use the std::find algorithm from the <algorithm> header to search for elements in STL vectors.

Can you show me a code example?

Sure! Here's a simple example:

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5};
    auto it = std::find(vec.begin(), vec.end(), 3);
    if (it != vec.end()) {
        std::cout << "Found: " << *it << std::endl;
    } else {
        std::cout << "Not found" << std::endl;
    }
    return 0;
}

What if I want to search for a string in a vector?

You can use the same std::find method. Just ensure your vector is of type std::vector<std::string>. Here's an example:

std::vector<std::string> strVec = {"apple", "banana", "cherry"};
auto it = std::find(strVec.begin(), strVec.end(), "banana");
