Calling Constructor without a pointer

[codelyoko373]

How exactly do I call the constructor of a class without making it a pointer and using the new keyword?

Am I unable to do this without making it a pointer?

You've asked an odd question.

struct my_class
{
  my_class( const std::string& s, int n ) { ... };
};

my_class my_object( "Hello", -7 );

Perhaps if you tell us what exactly it is you are trying to do...

At risk of repeated Duthoshas' information, any time you create an instance of a class (or struct), the constructor is called.

Like this:

someClass anInstance;

That called the constructor of someClass, and as you can see, no pointers or news to be seen.

Basically I have this Animation class that I'm using for a game and I've created a variable of it in a header file:

Animation animation;

I'm then doing what you mentioned in the source file:

Animation animation(this, 0.5f);

but despite doing that, I still get this error that "No default constructor exists"

[JLBorges]

In the header, use a declaration: extern Animation animation;

In the implementation file (.cpp), define it: Animation animation(thisxxx, 0.5f);
Note: we can use the keyword this only in non-static member functions.
