operands

问题 I just started learning assembly programming. I am using NASM on linux. I wrote this code that's basically meant to calculate the somethingth power of something and I know it's probably not exactly good, but I really don't care at this point, all I want is just SOME idea why I keep getting that error, because I have tried to modify and switch operands and operations and everything in the section where the problem is, but if anything that only gave me more error messages. As I said, I'm really

问题 When I study recursive functions in C from deitel c, I read this sentence: Standard C does not specify the order in which the operands of most operators (including +) are to be evaluated. But also the book says that: associativity of '+' from left to right Order of evaluation of operands: Could anyone explain why this is? 回答1: Order of evaluation and associativity are two different things, take the example: int x = func1() - func2() - func3(); //having int return types In this expression you

问题 I am making a small game in the console that takes place over several days. The game starts by initializing the miners ore and money amounts as 0. When he mines, my function chooses a random integer between 20 and 71 that will then award him that amount in 'ore'. I am trying to assign the ore that has been mined to my player's ore amount. I am having a reoccurring error that states that += is an unsupported operand for method and int. Full code and trace is below. Code import pyautogui as pag

问题 I am new to python so please be nice. I am trying to compare two Numpy arrays with the np.logical_or function. When I run the below code an error appears on the Percentile = np.logical_or(data2 > Per1, data2 < Per2) line stating ValueError: operands could not be broadcast together with shapes (2501,201) (2501,) data = 1st Array data2 = 2nd Array Per1 = np.percentile(data, 10, axis=1) Per2 = np.percentile(data, 90, axis=1) Percentile = np.logical_or(data2 > Per1, data2 < Per2) print(Percentile

I've been googling but I can't find anything. $x->func(&$string, $str1=false, $str2=false); what does that & before $string &$string do? 回答1: You are assigning that array value by reference. passing argument through reference (&$) and by $ is that when you pass argument through reference you work on original variable, means if you change it inside your function it's going

问题 I am a newbie to Python and have been recently attempting to create a BMI calculator, but I am having errors with the following code: def calculator(): weight = raw_input('Please enter your weight (kg):') if weight.isdigit and weight > 0: height = raw_input('Please enter your height (m):') if height.isdigit and height > 0: bmi = (weight) / (height ** 2) print "Your BMI is", bmi if bmi < 18.5: print 'You are underweight.' if bmi >= 18.5 and bmi < 25: print 'Your BMI is normal.' if bmi >= 25

问题 In C, I am able to do a trick with numbers: uint8_t value = 0 int delta = -1 uint8_t result = value + delta /* result will be 0xFF */ Is there a way of doing the same in Swift? Notice that the same approach doesn't work: let value: UInt8 = 0 let delta: Int = -1 var result: UInt8 = value + delta // Error, even typecasting in different ways... Is there a way to get C's behaviour for substraction in Swift? Thanks! 回答1: All signed and unsigned integer types have a bitPattern: constructor, which

问题 Every time I try this: long crypt(int *integer) { printf("Enter five digit integer:\n"); scanf("%i",integer); int digit1=integer/10000; int digit2=(integer%10000)/1000; int digit3=(integer%1000)/100; int digit4=(integer%100)/10; int digit5=(integer%10)/1; const char *digit1c[10]; const char *digit2c[10]; const char *digit3c[10]; const char *digit4c[10]; const char *digit5c[10]; (There's more but this seems to be the problem, I'll add the rest by request.) then it return this error: math2.h:44
