Templates cannot be compiled like any other source file. Both interface and implementation should live in the header file (although some split them in .hpp files for interface and .ipp files for implementation, and then include the .ipp file at the end of the .hpp file). How would the compiler know what classes to generate … Read more
What does no match for ‘operator>>’ (operand types are ‘std::istream’ {aka ‘std::basic_istream’} and ‘float*’) mean? [closed] solved What does no match for ‘operator>>’ (operand types are ‘std::istream’ {aka ‘std::basic_istream‘} and ‘float*’) mean? [closed]

In this introduction, we will discuss the basics of printing a string in a maximum of three lines and with a width parameter. We will … Read more
I just typed that pseudo code up really quickly, that’s why there was the def error. My issue was that I didn’t declare data as a global within the function. solved Class Access to Global Variables in Python
This is pretty hard to provide an absolute answer for without any CSS and HTML, but you should be able to set (where 40px is a sample height) .container{ height:40px; } If that fails, you likely have a rule with a higher level of specificity, so either alter that directly (dont), or extend the above … Read more
in class A: Intent myIntent = new Intent(classA.this, classB.class); myIntent.putExtra(“number”, maxpluseen) classA.this.startActivity(myIntent); in Class B: int getal; getal = getIntent().getExtras().getInt(“number”); …… solved Pass integer between classes in Java [duplicate]
The word for an object, field or property whose value doesn’t change for its entire lifetime is immutable. System.String is a classic example — any time you need a new string value, you actually get an entirely new object. solved What do we call unchangeable fields of a class?
Your program is missing constructor and hence the error. Also do note that you are probably referring to __repr__ and not __rep__. You final code should look something like this – class Car: # In your code, this constructor was not defined and hence you were getting the error def __init__(self,name,year,model): self.name = name self.year_built … Read more
You’ll probably need a vector like Soren mentioned. If you’re trying to get some averages for all employees (which that’s what I assume you’re trying to do), then let’s say we’re going to try and get an average for gross pay. You’ll need a vector global, like such: #include <iostream> #include <fstream> #include <iomanip> #include … Read more
I assume you are declaring a Nested class and use a array declared in ViewController into a class arrays. (I tried reproducing your error by adding your snippet into a ViewController, and luckily got the same error as you mentioned 🙂 ) Yes it is possible. see the following code. var array = [1, 1] … Read more
It appears that what you want is for your Derived class to support the following interface: someInfo si; someMoreInfo smi; Base* pB = new Derived; // Setting info pB->setInfo(si); // Set the `Base::c` member of `*pB` pB->setInfo(smi); // Set the `Derived::g` member of `*pB` // Getting info someInfo pB_si = pB->getInfo(); // Get `Base::c` from … Read more
First of all continue is an already occupied keyword, so, better rename your function. The continue statement shall occur only in an iteration-statement and causes control to pass to the loop-continuation portion of the smallest enclosing iteration-statement, that is, to the end of the loop. In our case, you trying to use a non-static member … Read more
