a/b – c/d = (ad – bc) / bd Then you need to reduce that to lowest terms (if you care about that). solved What would be the code to add and subtract fractions in c++ [closed]
We can understand what’s going on by looking at the anatomy of a 32-bit float. The value 3.0E9 in IEEE754 format is 0x4F32D05E, with exponent value 31 (you can use this online calculator to find the value). Now we have 23 sub-unity binary digits left for the mantissa. That means that the smallest increment, i.e. … Read more
Just set the value to the result of the comparison: button4.Visible = PlayersLevel > 1; button5.Visible = PlayersLevel > 2; solved How to make code more simple (if/else) [closed]
This will not work, as Show is an instance method, not a static mathod: register form = new register(); register.Show(); You probably meant: register form = new register(); form.Show(); Note: Your naming is non standard – types in .NET are normally in PascalCase – to be consistent, your should name the class Register. Additionally, using … Read more
wndclassex.lpfnWndProc; You do realize that this does precisely nothing, and wndclassex.lpfnWndProc pointer remains NULL, right? solved I need to help fix the code C++ Win32API
a + 1; You meant: a = a + 1; // or a += 1; The expression a + 1 results in a value, but you have not assigned that value to anything (a in particular). solved Why is this printing 0? [closed]
Use MSDN reference String.IndexOf Method int position = mystring.IndexOf(“E”); solved Getting character position in c# [duplicate]
In this context, 0 is a null pointer constant. It can be converted, with or without a cast, to any pointer type, giving a null pointer of that type. In modern C++, you can write nullptr to make it more clear that you mean a null pointer, not the number zero. There’s also a NULL … Read more
variable a is an integer (int), and integers take 4 bytes (regardless of what value is stored in it). Just because the specific value could be represented by fewer bits, it does not change the size of the variable. solved sizeof return type in C
you should have to return inside if because after if statement it again comes into while loop and add extra node at the end struct node { int data; // node format struct node* next; }; void insertAtEnd(struct node** headRef, int newData) { struct node* ptr; struct node* newnode; ptr = (*headRef); newnode = (struct … Read more
I missed that this method start with get_ Here is right answer. Just find “this HttpConfiguration” on entire solution. You can find extension method named start with “get_” If this solution not work.. find “this IDisposable” on entire solution. because HttpConfiguration class is implement of IDisposable 2 solved methods that give error [closed]
This is because you are trying to assign arrays instead of assigning their members: idArray = Int32.Parse(words[0]); should be idArray[i] = Int32.Parse(words[0]); and so on. Better yet, create EmployeeData class that has individual fields for id, name, dept, and so on, and use it in place of parallel arrays: class EmployeeData { public int Id … Read more
head=malloc(sizeof(node*)); Will allocate a space in memory to hold a POINTER to a object of type node. head=malloc(sizeof(node)); Will allocate space for the structure itself, and return to you the address of that memory space, and you will hold that in the head variable For more info, check this other question about Malloc. How do … Read more
FileInfo.Length is used to get the size of a file, the only way to change a file size is by modifying it’s content 2 solved Property or indexer ‘System.IO.FileInfo.Length’ cannot be assigned to — it is read only
It is valid syntax provided all the identifiers involved are bool identifiers, meaning a local variable, a parameter, a constant, field or a property that holds a bool value. If they’re not, then no, that is not legal syntax. I am also only referring to this part: if ( (x && y) || y || … Read more
