First of all, sorry for this stupid question. But I really need to know about the languages which are used to show execution flow of program in computer science books.
Example:
1 A = 4
2 t1 = A * B
3 L1: t2 = t1 / C
4 if t2 < W goto L2
5 M = t1 * k
6 t3 = M + I
7 L2: H = I
8 M = t3 - H
9 if t3 ≥ 0 goto L3
10 goto L1
11 L3: halt
Does this language have some specific standers? Is this a pseudo code or an intermediate form of code?
There are no technical rules for Pseudocode, unless you are attempting to conform to standards/syntax for a particular language.
Pseudocode is meant to be human readable and still convey the flow and meaning of the code.
Books that use Pseudocode typically conform to a Java, C, or Pascal-type (among others) structure to make the code easy to read for those familiar with the languages.
The naming conventions that I have seen in the past usually lean toward C or Java-esque naming conventions.
