示例

#include <iostream>
#include <string>
[[nodiscard]] constexpr auto get_digits(const std::string& string) noexcept
{
    std::string digits{};
    for (const auto& character: string)
    {
        if (character < '0' || character > '9') [[likely]]
            continue; // 条件性地跳过后续语句
        digits += character;
    }
    return digits;
}
int main() noexcept
{
    std::cout << get_digits("H3LL0, W0RLD!");
}

输出:

300
