如何在C++中将整数转换为数字数组

#include <iostream>
#include <vector>

std::vector<int> convertToDigits(int number) {
    std::vector<int> digits;
    
    while (number > 0) {
        int digit = number % 10;
        digits.insert(digits.begin(), digit);
        number /= 10;
    }
    
    return digits;
}

int main() {
    int number = 12345;
    std::vector<int> digits = convertToDigits(number);
    
    for (int digit : digits) {
        std::cout << digit << " ";
    }
    
    return 0;
}
