@文心快码error: overflow in constant expression 文心快码 在常量表达式中发生溢出错误。 在C++编程中,当你在常量表达式中使用了超出数据类型表示范围的数值时,编译器会报告“overflow in constant expression”错误。这种错误通常发生在编译时,因为编译器需要在编译阶段确定常量表达式的值。 原因 常量表达式中的值必须在...
(1) 问:如果我给一个int整形赋值0xFFFF,我得到一个信息"arithmetic overflow in constant expression"(常数表达式里算术溢出)。为什么编译器不是把它当做-1呢? 答:作为一个int整形,这个变量值的范围只能是从-32768到32767。0xFFFF的值是等于65535,所以太大了。如果你确实不想使用有符号的值,可以使用unsigned int,...

In a checked context, a System.OverflowException is thrown; if overflow happens in a constant expression, a compile-time error occurs. In an unchecked context, the operation result is truncated by discarding any high-order bits that don't fit in the destination type. For example, in the ...
