Aug 12, 2021 · Then it will apply unary - and you get -2147483648 of type long or long long. (Judging by your debugger output, it seems to be long long.) If you need it to have type int then as someone mentioned (-2147483647 - 1) is a commonly used trick. This tells us why -2147483648 would produce the value of −2147483648 as a long or long long.
Apr 8, 2013 · 4. It is absolutely legal to define negative constants with #define. What you discovered is most likely a bug in Xcode's code coloring, which will probably be fixed in one of the future revisions. Grammatically, the - is not part of the number. It is a unary operator. Hence the “Numbers” coloring doesn't apply.
The initializer converts this value from int to unsigned int. The rules for signed-to-unsigned conversion say that the value is reduced modulo UINT_MAX + 1, so -1 will convert to UINT_MAX (which is probably 0xffffffff or 4294967295 if unsigned int is 32 bits). You simply cannot assign a negative value to an object of an unsigned type.
Mar 2, 2013 · In Python 3 you have (at least) four choices: Use min (A) - 1. Use None, and whenever you compare two values, explicitly test for them being None. Define a new data type that consists of either an integer or -∞, and handles comparisons correctly. Modify the algorithm so that line 2 is eliminated. You will have to patch Heap-Increase-Key somehow.
Jul 21, 2016 · However, I would like the values to be negative, so they do not conflict with anything else. I could do it like this: typedef enum fruits{. apple = -1, banana = -2, lemon = -3, orange = -4. } fruit_t; But if I would like to add another fruit, I have to assign another value, and if I put one inbetween, I have to renumber most of it.
Jun 24, 2016 · 8. Define a enumerator with that value in the enumerator list and the result will be correct: typedef enum test {. minus_one = -1 , first, second, } soc_ctr_type_t; The reason you're seeing 255 is because the compiler chose a narrower unsigned type for this enumerator, because all it can see it first, second, which have the values 0, 1.
Mar 16, 2010 · Using a while loop at all is rare. for i in xrange(num_times): total += a # We do this a times, giving us total == a * abs(b) if b < 0: # If b is negative, adjust the total to reflect this. total = -total print total or maybe. a * b
Jul 13, 2015 · 1. This isn't specific to C++, but rather about 2's complement form. In 2's complement, the most-significant bit doesn't merely indicate the sign (that the value is negative) but is rather that power of 2 (that is, for an 8-bit 2's complement number, the most significant bit would represent -2^7). To make the most negative number, only the most ...
Nov 8, 2017 · 42. To explain how negative indexes work, you first have to learn (or remember) that for any array or pointer a and index i, the expression a[i] is equal to *(a + i). That means that you can have a pointer to the middle element of an array, and use it with a positive or negative index, and it's simple arithmetic. Example: int a[3] = { 1, 2, 3 };
Apr 1, 2011 · #define MAX_NON_NEGATIVE_INT ((int)(((unsigned int)-1) / 2)) I won't insult your intelligence by explaining what it's doing! Edit: I should have mentioned that I cannot use any standard classes, because I'm running without the C runtime.
