Solution: Container ship is a class contains objects of other class types as its members.

Solution: There are three types of constructor in C++. They are the Default constructor, Parameterized constructor, Copy constructor.

Solution: There can be multiple constructors of the same class, provided they have different signatures.

Solution: Constructor name should be same as the class name.

Solution: The derived class inherits everything from the base class except the given things.

Solution: Templates are used for creating generic classes to handle different types in single classes.

Solution: Every string template is used to replace the string with another string at runtime.

Solution: template<> syntax is used.
An example for calculating max of two ints, floats, doubles, or any other number type where T indicates the type of the parameters passes.
template 
T max(T a, T b){
return a > b? a : b;
}

Solution: The compiler can determine at compile time whether the type associated with a template definition can perform all of the functions required by that template definition.

Solution: The name of the parameter that the template should take same as the template.
