Answer:
The answer to this question can be given as:
Class definition:
public class Averager //define class Average.
{
private int sum = 0;
//define variable sum.
private int count = 0;
//define variable count.
public int getSum() //define function getSum().
{
return sum; //return value.
}
public void add(int x)
//define function add().
{
sum = sum + x; //calculate sum
count=count+1; //increase value of count.
}
public int add(int x)
//define function add().
{
return count; //return value.
}
public double getAverage() //define function getAverage().
{
return (double)sum/count; //return value
}
}
Explanation:
The above class definition can be described as:
- In the above class definition first we define a class that is " Averager". In this class we define two integer variable that is "sum and count" and assign a value that is 0. Then we define a functions :
- First we define getSum() function in this function we does not pass any value and the return type of this function is int that will return an integer value.
- Then we define add() function we use this function two times but both functions have different from each other.
- In first time implementation, we define this function and the return type of this function is void which means it does not return any value. In this function, we calculate the sum value and increase the value of the count variable by 1.
- In second time implementation, we define this function and the return type of this function is int which means it will return a value. In this function, we will return the count variable value.
- At the last, we define a getAverage() that calculates the average of the added values in the sum variable and returns its value.
No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.
It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.
Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.
Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.
- In Python int, float, and complex are the data types used to declare number type variables.
- SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.
- To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.
- JavaScript uses a single data type called 'number' to declare numbers.
- In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.
So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.

Answer:
Britain also happened to have a wealth of coal, iron, and other resources in a relatively small area, which would help kick-start the Industrial Revolution. Its growing Colonial Empire also provided a ready-made (and captive) market for surplus goods, providing further impetus for entrepreneurs and new industrialists
The correct answer is "opinion".
