exception基类不包含以string为参数的构造函数,所以,不能throw exception(“Error”);一般不从这个根类直接继承,从下面的派生类继承。 error: no matching function for call to ‘std::exception::exception(const char [4])’ 改成: std::logic_error
logic_error。逻辑错误是由于程序内部逻辑而导致的错误。逻辑错误是可以避免的,且在程序开始执行之前,能够被检测到。 domain_error:专业领域内的范畴 invalid_argument:无效参数,比如讲bitset以char而非0或1进行初始化 length_error:可能超越了最大极限,比如对着某个字符串附加太多字符。 out_of_range:参数不再预期范...
logic_error 的派生类: runtime_error 的派生类:
std::cout << "Conf set 'default_topic_conf' failed: " << error_str << std::endl; } // 创建消费者客户端: m_consumer = RdKafka::KafkaConsumer::create(m_config, error_str); if (m_consumer == nullptr) { std::cout << "Create KafkaConsumer failed: " << error_str << std::en...
std::string getUUID(); 这是Message.cpp中相应的实现: 代码语言:javascript 复制 #include "Message.hpp" #include <iostream> #include <string> #ifdef HAVE_UUID #include <uuid/uuid.h> #endif std::ostream &Message::printObject(std::ostream &os) { ...

你好,我想知道在VHDL中信号声明是如何工作的。它是否意味着延迟,因为它是一个内部信号?信号有内部存储器吗?示例:signal C: std_logic; process (A) C<=A; else B<= '0'; 浏览0提问于2012-02-20得票数 2 回答已采纳 2回答 <cstring>头和<string>头是相同的吗? 、、、 两者之间有什么区别,还是...
