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:
The correct answer is letter "A": controlling.
Explanation:
There are four (4) basic management skills: <em>Planning, Controlling, Organizing, </em>and <em>Leading. </em>
Controlling implies reviewing the objectives the firm has established to evaluate the progress. It also involves measuring the resources the firm has available for reaching its goals and verifying if they will be enough to get to the finish line, otherwise, the company should find more efficient forms of allocating resources and funding its operations.
In other words, <em>the controlling skill of management sets the standards of performance within the institution.</em>
Answer:
Ram/cpu/gpu... Many many things she can do
Explanation:
It may be a issue of internet bandwith, if this new game requires a insane ammount of internet then it may run low FPS (frames per second) and make myra's game look slughish,but anouther issue may be the ram or cpu, like if this is a new game and you've always played like simple games, so your running on persay a core i3 or i4, it aint gonna cut it on a newer game, you gonna need a probably core i5 or i7, or be like any sane person and switch to amd, it may be a bit pricy but if you want nice clean gaming, then amd is the way to go
Also while you are at it get a ssd
I hope this helps "-"
