Variable Assignments Assigning a value to a variable is indicated in pseudocode using an arrow symbol (←). The arrow points from the value being assigned towards the variable it is being assigned to. The following line of pseudocode should be read as 'a becomes equal to 34'.

Definition: Pseudocode is an informal way of programming description that does not require any strict programming language syntax or underlying technology considerations. It is used for creating an outline or a rough draft of a program.
Pseudocode literally means 'fake code'. It is an informal and contrived way of writing programs in which you represent the sequence of actions and instructions (aka algorithms) in a form that humans can easily understand. You see, computers and human beings are quite different, and therein lies the problem.

In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct.
Explanation: The answer is ENDIF.
Expert-verified answer The statement about pseudocode which is not correct is: B) Pseudocode should be properly formatted. A pseudocode can be defined as a description of the steps contained in an algorithm through the use of a plain or natural language.
Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is a "text-based" detail (algorithmic) design tool. The rules of Pseudocode are reasonably straightforward. All statements showing "dependency" are to be indented. These include while, do, for, if, switch.

In a flowchart the symbol that represents an assignment statement is an oval.
Within most programming languages the symbol used for assignment is the equal symbol.
Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is a "text-based" detail (algorithmic) design tool. The rules of Pseudocode are reasonably straightforward. All statements showing "dependency" are to be indented.
Several keywords are often used to indicate common input, output, and processing operations.Input: READ, OBTAIN, GET.Output: PRINT, DISPLAY, SHOW.Compute: COMPUTE, CALCULATE, DETERMINE.Initialize: SET, INIT.Add one: INCREMENT, BUMP.
As they put it, “why write code twice?” That might be correct in the case of simple, straightforward problems. However, as the complexity and the size of the project increases, programmers come to realize how generating pseudocode makes writing the actual code much easier. Pseudocode helps you realize possible problems or design flaws in the algorithm earlier in the development stage, which saves you more time and effort on fixing bugs and avoiding errors down the road.
Pseudocode is an underestimated and under-utilized tool within the programming community , but a clear, concise, straightforward pseudocode can make a big difference on the road from idea to implementation — and a much smoother ride for the programmer.

Pseudocode is a technique used to describe the distinct steps of an algorithm in a manner that’s easy to understand for anyone with basic programming knowledge.
At its core pseudocode is the ability to represent six programming constructs (always written in uppercase): SEQUENCE, CASE, WHILE, REPEAT-UNTIL, FOR, and IF-THEN-ELSE. These constructs — also called keywords —are used to describe the control flow of the algorithm.
Sometimes, programmers even include the pseudocode as a docstring at the beginning of the code file. Easier Bug Detection: Since pseudocode is written in a human-readable format, it is easier to edit and discover bugs before actually writing a single line of code.
Although pseudocode is a syntax-free description of an algorithm, it must provide a full description of the algorithm’s logic so that moving from pseudocode to implementation is merely a task of translating each line into code using the syntax of any given programming language.
It is an informal and contrived way of writing programs in which you represent the sequence of actions and instructions (aka algorithms) in a form that humans can easily understand.
This is possible because you are in full control of everything, which is one of the great features of pseudocode.
Taking up coding challenges online is a great way to learn how to program because, as they say, practice makes perfect. But when you try your next challenge, don’t forget to implement pseudocode in the process!
Pseudocode acts as the bridge between your brain and computer’s code executor. It allows you to plan instructions which follow a logical pattern, without including all of the technical details.
If you fail to properly understand the question, you won’t be able to work through the problem and figure out the possible steps to take. Once you identify the main problem to be solved you'll be ready to tackle it.
First, you need to understand that all a function does is (optionally) accept data as input, work on the data little by little, and finally return an output. The body of the function is what actually solves the problem and it does so line by line.

Hence we can say that the purpose of writing pseudocode is that it is easier for people to understand than any specific programming language code
As you know, pseudocode is the way of expressing a program or code so that it could be easily understood by programmers of every programming languages out there.
Conditions and loops must be specified well ie. begun and ended explicity as in given pseudocode examples :
In Pseudocode, this item is a name given for a place in memory.
In pseudocode, a Repetition construct allows a choice between performing an action or skipping it.
The STBA mnemonic stores a Byte from the accumulator to a memory location.
Assembly language instructions are executed directly by the hardware of a particular computer.
The input to an assembler is an assembly language program.
A Comment in Assembly Language is an instruction that indicates which instruction to process next.
In Pseudocode, this construct can have an If-Then or an If-Then-Else structure.
For starters, we can use the plus + and minus - symbols as operators to perform addition and subtraction in pseudocode, just like in math. For example, we can add two variables together to create a third variable as shown in this example:
In pseudocode, we use the asterisk *, sometimes referred to as the star symbol, to multiply two values together. For example, we can find the product of two values as shown in this pseudocode block:
There is one other operator that is used commonly in pseudocode - the modulo operator. The modulo operator is used to find the remainder of a division operation. If we think back to math again, we’ve probably learned how to perform long division when dividing two values.
Finally, just like in mathematics, we must also be aware of the order that these operators are applied, especially if they are combined into a single expression. Thankfully, the same rules we learned in mathematics apply in programming as well. Specifically, operators in pseudocode are applied in this order:
