Why are there multiple ways of initializing variables in c++ instead of just one?
From my knowledge you can do these:
int x = 0;
int y (2);
int c {3};
Thanks!
Oh, it is because , all of datatypes are an object.
They all have blind initializers, that is same as the default-constructor(initializer) of the classes.

What is the difference between int &r and int r?

First keep in mind that int& r and int &r are syntactically the same thing: r is a variable of type int&. So r is an integer reference.

I read the following code in c++:
bool result(false);
is result initialized as false?
but are there any benefits to do it instead of:
bool result = false;
can anyone help?
