3.2、对于size()函数来说,其返回的是string:size_type类型(无符号整数类型),标准库中定义自己配套的类型,就是为了保证与机器无关的特性。在c++11中允许使用auto或者decltype来推断变量的类型:auto len = line.size();值得注意的是,如果用一个负值,比如s.size()<n(负数n),那么结果肯定是true,因为负值会转换成...

cpp标准库中提供了一系列的异常类。在<exception>头文件中包含:exception,bad_exception,bad_alloc异常类型的定义,<stdexcept>文件中定义了logic_error,domain_error,invalid_argumentlength_error,out_of_range,runtime_error,overflow_error等异常,我们可以选择一个合适的类型来继承,从而实现自定义异常类型。 view plain...

13.2.2.3 std::length_error,当创建了太长的 std::string 时,会抛出该异常。 13.2.2.4 std::out_of_range,该异常可以通过方法抛出,例如 std::vector 和 std::bitset<>::operator。 13.2.3 不可通过读取代码检测异常 13.2.3.1 std::overflow_error,当发生数学上溢时,会抛出该异常。
