How do I use std::remove_copy_if in C++?

Can you explain how to use std::remove_copy_if in C++?

Sure! std::remove_copy_if is used to copy elements from one range to another, excluding elements that satisfy a certain condition.

What parameters does std::remove_copy_if take?

It takes five parameters: the input range's start and end iterators, the output iterator, and a predicate function.

Can you give me a code example?

Of course! Here's a simple example:

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

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5};
    std::vector<int> result;
    std::remove_copy_if(vec.begin(), vec.end(), std::back_inserter(result), [](int x) { return x % 2 == 0; });
    // result now contains {1, 3, 5}
}
