“narrowing conversion”错误是指在类型转换过程中,目标类型的表示范围小于源类型,导致源类型中的某些值无法被目标类型完全表示,从而发生数据丢失或截断的现象。这种转换通常会导致编译器的警告或错误,因为它可能引入潜在的运行时问题。 2. 为何将-1从'int'转换为'char'会导致“narrowing conversion”错误? 在C++中,...

You have made a call to an overloaded method, but the compiler cannot find a method that can be called without a narrowing conversion. A narrowing conversion changes a value to a data type that might not be able to precisely hold some of the possible values....
