The macro you defined lacks brackets to keep the arithmetic working as you want. Remember preprocessor macros are doing text replacement solely. So what you’ll get from calling it as you shown expands to int answer (2 + 4 * 2 + 4); and according operator precedence the result is 14. Write your macro as … Read more
When in doubt, try it out. In general, the higher precision will take precedence. So if you have a int and a double, the double is higher precision, so the result will have that form. int number_1 = 3; double number_2 = 1.5; std::cout << number_1 * number_2; Output: 4.5 1 solved What is the … Read more
The Loop in checkerstarts with i=0, i.e. you do a% 0 which will result in a divide by zero exception. solved Why will this code crash? (I am new to C++)
You could treat the whole page/web request as a string and do something like this: https://msdn.microsoft.com/en-us/library/bb546166.aspx It might not be efficient and it would search CSS classes and everything else but it might be a starting point. Else you need to use the agility pack and scrape through each not and check each bit of … Read more
So the situation is a loop like this: for (rows = columns + 1; rows < height; rows++) { // do something } I think you’re asking why the loop executes fewer times when the loop says for (rows = columns + 1;… than when it says for (rows = columns – 1;…. The reason … Read more
You don’t need to recreate the array, and you don’t need to sort anything (the description even tells you that you shouldn’t: “Dino’s computer cannot perform this arrangement”). Consider what happens if you turn the problem around slightly. Instead of a[i] being the i:th number, let it say how many is there are in total. … Read more
C# is a case sensitive programming language. You wrote transform.Position instead of transform.position. You also tried to make operations on transform.position which is invalid. If you want to make an operation on the position then you must declare x or y. So, transform.position.x + 5 is valid However, transform.position + 5 is invalid. solved Unity … Read more

3912039621 + 3499050777 is not 7824079242 but 7411090398 and there for c# is correct 7411090398 % (2^32) = 3116123102 Here is an python example to convince you 6 solved Addition of two unsigned integer result exceeds and has different value [closed]
The sample you provided have some mistakes. addValues method in your code is not accepting any parameters but your code is trying to pass 2 parameters. I have re wrote your code.

The order in which the arguments passed to a function are evaluated is not specified, and the order of evaluating the operants of + is unspecified, too. So in printf(“%d %d”, i+1, i-1), for example, you cannot rely on the order of evaluation of the arguments; i+1 might be evaluated after i-1, actually; You will … Read more
std::vector<int> b = a; will this creates b as a copy (new object with same contents) of vector a or as a reference to it? that create b as a new vector being a copy, so b.append(1); does not change a solved Std::vectors – copying vs creating a reference
(I did that answer while R 0x… and W 0x… was given on the same line rather than two) If you are sure each line of the file contains R<space>0x…<space>W<space>0x… then you can do int main() { FILE * fp = fopen(“in”, “r”); if (fp == NULL) { puts(“cannot open ‘in'”); return -1; } char … Read more
