如何在C++中删除数组中小于X的整数？

#include <iostream>
#include <vector>

void removeElements(std::vector<int>& arr, int x) {
    int i = 0;
    while (i < arr.size()) {
        if (arr[i] < x) {
            arr.erase(arr.begin() + i);
        } else {
            i++;
        }
    }
}

int main() {
    std::vector<int> arr = {1, 2, 3, 4, 5};
    int x = 3;

    removeElements(arr, x);

    std::cout << "Updated array: ";
    for (int num : arr) {
        std::cout << num << " ";
    }
    std::cout << std::endl;

    return 0;
}

Updated array: 3 4 5
