The use of the inheritance to have a structure inherit attributes and methods of classes above it.
One of the key milestones in the period in which the object-relational model was created was the creation of a data
model that closely represented the real world. In this approach, objects were created in which both data and its
relationships were all contained in one place. These data models were becoming a norm to be stored on the web. They
also incorporated support for star schemas within data warehouses. Objects that had similar characteristics were
grouped into classes, where they had a shared structure of attributes and behaviors.
Answer:
for (type variable-name : array-or-collection)-On each iteration the next element can be accessed using the specified variable.
Explanation:
the general structure of a for-each loop header is represented as :
for (type variable-name : array-or-collection) - On each iteration the next element can be accessed using the specified variable.
In other words it can be represented as:
for (type variable-name : array-or-collection)
{
//On each iteration the variable-name will contain the next value in the array or collection and this value can be referenced in the loop body using the variable-name.
}

Following are the program to calculate the power of two:
Program Explanation:
- Defining an integer variable "i" that hold an integer value.
- Defining a for loop that checks "i" value in between 20, inside this it calculates power of two.
- At the last use print method to print its value.
Program:
i=1#holding integer value in i
for i in range(20):#defining a for that starts 1 to 20
i = 2 ** i#calculate power of 2 in i variable
print(i)#print value
Output:
