In most cases, there is no “default” value for an int object. If you declare int i; as a (non-static) local variable inside of a function, it has an indeterminate value. It is uninitialized and you can’t use it until you write a valid value to it. It’s a good habit to get into to … Read more
This line here d = w[L] /v[L]; takes place over several steps d = (int)w[L] / (int)v[L] d=(int)(w[L]/v[L]) //the integer result is calculated d=(double)(int)(w[L]/v[L]) //the integer result is cast to double In other words the precision is already gone before you cast to double, you need to cast to double first, so d = ((double)w[L]) … Read more
There are a few different ways to do it. For example, if your list includes only numbers: >>> my_list = [1, 2, 3.25] >>> all(isinstance(item, int) for item in my_list) False >>> other_list = range(3) >>> all(isinstance(item, int) for item in other_list) True >>> Anyways, this solution doesn’t work as expected if your list includes … Read more
The question is poorly worded, and hence the confusion in the answers so far. The question should be “are reads and writes to a variable of type int? guaranteed to be atomic?” No, absolutely not. The spec is extremely clear on this point: Reads and writes of the following data types are atomic: bool, char, … Read more
Something is probably just converting that to int(11) for you. Since you can’t have 255 visible digits in an int, the maximum value will be 2147483647. If you need more than that you can set it to be unsigned, since I’m assuming you have no negative ids and then you can have up to 4294967295. … Read more
std::stoi was introduced in C++11. Make sure your compiler settings are correct and/or your compiler supports C++11.
In Swift 2.0, toInt(), etc., have been replaced with initializers. (In this case, Int(someString).) Because not all strings can be converted to ints, this initializer is failable, which means it returns an optional int (Int?) instead of just an Int. The best thing to do is unwrap this optional using if let. I’m not sure … Read more
You are missing the parentheses of the method call: ToString() Without the parentheses, the expression is a method group — that is, a reference to one or more overloaded methods.
You are never assigning the values inside the test2 array. You have declared it but all the values will be 0. Here’s how you could assign a random integer in the specified interval for each element of the array: int Min = 0; int Max = 20; // this declares an integer array with 5 … Read more
According to the Swift Documentation Int In most cases, you don’t need to pick a specific size of integer to use in your code. Swift provides an additional integer type, Int, which has the same size as the current platform’s native word size: On a 32-bit platform, Int is the same size as Int32. On … Read more
