In C, the most important rules are:
In c, variables are declared by stating their type, followed by a name that you choose, optionally followed by a array specification, optionally followed by an initializer.
int a;
int *a;
int a[3];
int a = 1;
char a[] = "This is a test";
double a = 1.234;
struct _a {
int b;
float c;
} a;
In C++, a variable is declared by writing (inside or outside a function) int x;
Alternately, you can also use long, float, double, string... x; (example: float x;)
<Data_Type> <Variable_Name>
ex:- int score
we declare variables using
integers-whole numbers
characters -letters
double-decimals
float-fractions
strings-words
You declare a variable in C by declaring the variables type followed by its name. A declaration is also a statement, thus you end the declaration with a semi-colon. You may also include an optional initialiser in a variable declaration.
int x; // declare an uninitialised integer named x.
int y = 42; // declare an initialised integer named y with initial value 42.
Note that you must initialise all variables before you use them. In the above example, we can initialise x via assignment:
x = 100;
Now we can use x in other expressions.
Pseudo code is intended to be a short-hand representation of the process. It is often intended to be readable by non-programmers. As such, it is much less strict as far as syntax or structure goes and can vary widely from author to author.
Variables are typically omitted but if you feel the need to include variables any way that makes it clear will do. Any of the following should be clear:
set value to true, var = true
It depends on the programming language, please re-ask this question with the language you are asking about in either the question or the categories.
It is a request for memory and space in the computer. It also creates storage to be referred to later.
Pseudocode is any kind of fake or non-existent programming language so you can declare and use variables however you want.
Pseudocode is not a programming language (it's specifically intended for human interpretation), so there is no need to declare variables, you simply define them as and when you require them. For instance: Let x = 42 Let y = x * 2
HTML is not a programming language and as such does not allow you to declare variables.
Pseudo code cannot be processed by a machine, it is solely intended for processing by humans.
implicit means you must declare variables before using them while explicit is not a must you declare variables before using them
No. There is no "right way" and "wrong way" of writing pseudo code, let alone qualifying with "absolute". However, a pseudo code is "wrong" if it cannot be understood, or it is incorrect in semantic (what the code tries to describe, solve, etc)

It doesn't. Pseudo code isn't a programming language, it is just there to give an idea of how you could write a program.
what's the difference between flow chart and structure diagrams and pseudo code
No. There is no "right way" and "wrong way" of writing pseudo code, let alone qualifying with "absolute". However, a pseudo code is "wrong" if it cannot be understood, or it is incorrect in semantic (what the code tries to describe, solve, etc)
Pseudo code does not have key words, you make it up, that's why it is pseudo.
pseudo code algorithm to create a linked list
You are going about this backwards. First, define the program. Second, describe its algorithm. Third, if needed, write pseudo code. (Sometime, algorithm and pseudo code is the same process.) Fourth, or third, write real code.
Source code is a sequence of executable instructions written in a particular language. Pseudo code is a sequence of non-executable instructions. It is also called algorithm written in plain English
Pseudo city codes are 3 or 4 charachters long
