Web如果int可以表示char和unsigned char类型的所有值，则此转换不会更改这些值。如果char是无符号的，并且有8位，cnt有值255，因此i用值253初始化，循环从253到0运行254次，然后i--将值255再次存储到i，测试i < cnt的计算结果为false。循环打印507，然后75932385. WebWhile each claim may stand on its own as a separate example, it is to be noted that, although a dependent claim may refer in the claims to a specific combination with one or more other claims, other examples may also include a combination of the dependent claim with the subject matter of each other dependent claim or a combination of each feature …
Arithmetic on Unsigned Integers Can Yield Incorrect Results
WebAug 2, 2024 · In the following example, the result of the expression ( 0 - 1) is implicitly converted from int to unsigned int when it's stored in num. This causes the bit pattern to be reinterpreted. unsigned int u3 = 0 - 1; cout << u3 << endl; // prints 4294967295 The compiler doesn't warn about implicit conversions between signed and unsigned integral types.
