myInt = new int(); // Invoke default constructor for int type.
This statement is equivalent to the following statement:
myInt = 0; // Assign an initial value, 0 in this example.
Using the new operator calls the default constructor of the specific type and assigns the default value to the variable. The default value of an integer is 0 BTW.
The difference is that you can't initialize and set anything but the default value value using the new operator.

The condition is that this lines must be withing some function or constructor otherwise you can not use i.ToString(); on an instance member directly in class code.

This code is incomplete, no constructor, no referencing and conversion can not be made so explicit.

It is perfect code snippet which creates the //default constructor//.

@All.
int x = new int();
=> new gives x default value of x.
int x = new int();
=> new gives x default value of x.
