算术表达式在转换为更宽的类型之前可能会溢出。 在C 和 C++ 中,算术运算是使用最宽的操作数类型进行求值的,而不使用为结果赋予的类型的宽度。 当结果转换为更宽的类型时,它指示开发人员预计此运算可能溢出更窄的操作数类型。 lnt-arithmetic-overflow检查是由 C/C++ 代码样式选项中的“算术溢出”设置控制的。 有...

An arithmetic expression may overflow before being converted to a wider type. In C and C++, arithmetic operations are evaluated using the widest type of the operands, not the width of the type assigned the result. When a result is converted to a wider type, it indicates the developer expects...
