Programming
- Algorithm
- An Algorithm is what people use when creating something, for
example a game. Normally, a Algorithm is a list of rules that
you have in order to solve a problem, it is written in
pseudocode or a flow diagram. Pseudocode is not a type of
coding language but a way of describing a set of instructions.

- Programming Languages
- A programming language is a specially written code used for writing applications. C++ and Java are
examples of programming languages. These are known as high level languages because they have
been developed to be a little like a human language.High level languages are much easier to use than
a low level language such as Machine Code, or Assembly Language. The advantage of a low level
language is that it runs very fast on the computer.

- Control Flow in Imperative Languages.
- Algorithms use control flow to make decisions about which order to
do things. They can repeat actions or start new actions based on new
information.Computer programs use sequence, selection and
iteration to control the flow of the program.
- Sequence: The most basic algorithm uses
sequences to present a list of instructions to be
followed one after the other, step by step.
- Selection: A selection is used to make choices based on
information. An algorithm can be made more intelligent by
using IF, THEN and ELSE to repeat instructions or move to
different parts of the program.
- Iteration:Iteration is the process of
repeating sections of a program to
achieve a particular target or goal.

- Handling Data In Algorithms
- Constants: Constants are symbolic names given to
data where the value of the data cannot change
during the execution of the program. Many
constants such as PI are built into programming
languages.
- Variables Variables are symbolic names
given to data where the value of the data
stored may change during the execution of
the program. In effect, a variable is a named
area of memory used to store data.
- Data Types: Different types of data
are represented in different ways
inside a computer and need varying
amounts of memory to store them.
They also have different operations
that can be performed upon them.
All values that belong to the same
data type will be represented in the
same way.
- The most commonly supported data types in
programming languages are:

- Testing
- There are different types of errors, or bugs, which can prevent
computer programs from working in the way they should. one of
these errors is called a Syntax error. These are errors that occur
mainly when your code a a gramaticall error, the error occurs as
the program does not undersatnd the code as is is not correclty
spelled, for example the use of capital letters.
