C++中,显式地进行强制类型的转换有以下两种形式: type (expr) ; //函数形式的强制类型转换 (type) expr; //C语言风格的强制类型转换 比如: char c = '12'; int b = (int)c; float f = float(b); C++的新式强制类型转换 命名的强制类型转换具有如下形式: cast-name<type> (expr); cast-name可以...
首先,当eval()报错 “name is not defined” 时,表示你在执行的表达式中,使用了一些未定义的变量名。例如,表达式a + b中的a和b如果没有被定义,Python 就会抛出该错误。 第二步:准备环境与输入 在这一步,我们创建一个表达式,其中引用了未定义的变量。 # 定义一个包含未定义变量的表达式expr="a + b"# '...
