What you are looking for is a tagged union also called a variant. It allows you to store multiple data types at the same location just like a regular union but includes an additional but separate data member that indicates it’s type. The C++ Standard Library does not include variants but they are easy enough … Read more
The question boils down to: If I write this: int x = ‘ÿ’; x will be -1 but I’d like it to be 255. It’s -1 because ‘ÿ’ is a char of value 0xff. But as char is signed on your platform, sign extension takes place when you assign it to an int. The solution … Read more
You can use strconv from the strconv package package main import ( “fmt” “strconv” ) func main() { a := 4 b := 3 c := “1” fmt.Println(c + strconv.Itoa(a) + strconv.Itoa(b)) } Or you can use Sprintf from the fmt package: package main import ( “fmt” ) func main() { a := 4 b … Read more
int() function in Python and Python3 converts a number in given base to decimal. So,in your code: the first line is for asking the user whether how many binary numbers he wants to convert to decimal. Then you are setting the range in for loop. Then you are asking for input with base 2 to … Read more
I managed to achieve what I wanted using the following: public bool DataIsValid(string s, Type someType) { o = 0; // a class member object variable try { o = Convert.ChangeType(s, someType); } catch { return false; } return true; } //using the object variable double someDouble = (double)0; //some more code Thanks for the … Read more
public ActionResult Index() { var EmployeerId = SessionPersister.Email_ID; //Convert.ToInt32(EmployeerId); int EmpId=int.Parse(EmployeerId); db.Job_Det.OrderByDescending(j => j.Job_ID).ToList().Where(x => x.Employeer_ID = EmpId); return View(); } solved Cannot implicitly convert type ‘string’ to ‘integer’ [closed]
No, Convert.ToInt32(text) will just try to parse your text to an int, like: Convert.ToInt32(“032”) will return 32 as int but Convert.ToInt32(“Brian”) will throw an exception. I assume that you want to have some kind of hashing, when you say “different words to the same int”. Try GetHashCode(). It will return the same value if you … Read more
If you want to control the precision then include #include <iomanip> and use std::cout << std::setprecision(17); to set the number of digits you want. Also float has 6 significant bits precision whereas double has 12. So whenever your string has more than 6 digits in decimal there is a possibility of loosing the precision. 7 … Read more
Variable a was not initialized. It has an indeterminate value. 1 solved What are potential issues with the following code? short foo() { short a,b,c; b=10; c = a + b; return c; } [closed]
If I understand right you just want to determine which list has to be filled up depending on the datetable result set. So, when calling the function why don’t add (help)-parameter which determines where it was called from and depending on this variable the function will know what list to use. solved List to List
def Convert(s): p = s.split(“,”) return (int(p[0]), int(p[1])) 1 solved How to convert ‘1,2’ into a tuple (1,2) in python?
You want to transfer a String into a Treecreat? You should give Treecreat a constructor like this. public Treecreat(String yourString){ this.myString = yourString; } So the String is in Treecreat and you can work with it in your method, with call the method in this way: add(new Treecreat(data). solved How can we convert a string … Read more
