Answer:
True is the correct answer for the above question.
Explanation:
- The social website is used to connect the people using the internet to communicate. With the help of this, any people can communicate within the world's people.
- If anyone posts their pictures or comment on this type of website, then they need to care for that post or pictures. it means he needs to make decisions to choose the pictures or comments while posting.
- It is because when the user posts the wrong comments or pictures, then their popularity is less in front of the other people called society.
- This concept is also said by the question, hence it is a true statement.
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 answer is 2,3,4 and the next one is 1,2 and 4
Explanation:
Just did it
EDG 2021
The
piston engine uses the crankshaft to convert the reciprocating motion of the
piston into rotary motion.
<span>The
crankshaft is used to convert reciprocating motion of the piston into rotary
motion, while the conversion process is called torque, which is a twisting
force. Aside from crankshaft, there are a total of four parts of the engine
that work together in order to convert the reciprocating motion into rotary
motion namely cylinder, or also called the chamber of the piston, the piston itself,
and the connecting rod.</span>
Answer:
ArrayList a contains [2, 3, 3, 3, 4, 5, 3, 2, 1]
Explanation:
Given
The removeValue method
Required
The content of ArrayList a, after the method is called
From the question, we understand that arraylist a is:
![a= [2, 3, 4, 3, 3, 4, 4, 5, 4, 3, 2, 1]](https://tex.z-dn.net/?f=a%3D%20%5B2%2C%203%2C%204%2C%203%2C%203%2C%204%2C%204%2C%205%2C%204%2C%203%2C%202%2C%201%5D)
The function fails when the value to be removed appear consecutively in the list.
4 appears in index 5 and 6 of the list. Only one of the 4's will be removed
So, the updated list will be: [2, 3, 3, 3, 4, 5, 3, 2, 1]
