Programming Fundamenals

 

A computer is a Programmable machine.It has the ability to store,retrieve,and process data.you may already know that you can use a computer to type documents, send email,play  games,and browse the web.

How do they it? 

 

 

computer programming 

computer programming is the process of developing and implementing various set of  instructions to enable a computer to do a certain task.

Programs are written t solve problems or perform tasks on a computer.
 

what is Programming languages?

 Programming languages concepts

 Programmers translate the solution or tasks into a language the computer can understand.

A Programming language is a set of rules that provides a way of telling a computer what operating to perform.

A programming language is a set of rules for communicating an algorithm.

For web Development

Scripting Language Vs Programming language

 Most important basic elements for programming languages are

Programming Environment

An integrated development environment is an application used to create software.An IDE(Integrated Development Environment)can often support different languages.IDEs have a number of different tools and function hat assist a developer in the creation of software.

Data Types 

A data type constrains the values that an expression such as a variable or a function might take . this data type defines the operations hat can be done on the data the meaning of the data and he way values of that type can be stored.A data type provides a set of values from which an expression.

Boolean (e.g:- True or False)                                                                                                         Character(e.g:- a)                                                                                                                           Date(e.g:-21/12/2020                                                                                                         Double (e.g:- 21.847773734477878987)                                                                               Integer:-(e.g:-337884)                                              

Variables

A variable's storage location may be referenced by several different identifiers a situation known as aliasing .Assigning a value to the variable using one of the identifiers will change the value that can be accessed through the other identifiers.

Keywords

As a website owner and content creator you want he keywords on your page to be relevant to what people are searching for so they have a better chance of finding your content among the results.

Logical and Arithmetic operators

Image arithmetic applies one of the standard arithmetic operations or a logical operator  to two or more images.logical operator are often used to combine two binary images in the case integer images the logical operator is normally applied in a bitwase way.

 If else conditions

 the if/else statement extends the if statement by specifying an action if the if (true/false expression or yes/no) is false with he if /else statement the program will execute either the true code block or the false code block something is always executed with an is /else statement.

 Loop

A loop is used for executing a block of statements repeatedly until a particular condition is satisfied .for example when you are displaying number from 1 to 100 you may wan set the value of a variable to 1 and display it 100 times increasing its value by 1 n each loop iteration

 Numbers,Characters and Arrays

Numerical digits are the number text characters used to show numerals.for example the numeral "56" has two digits 5 and 6.

An arrangement of objects ,pictures or numbers in columns and rows is called an array.Arrays are useful representations of multiplication concepts.

Input Output operations

Input  refers to the signals or instructions send to the computer .Output refers to the signals send out from he computer. this term is also known as operations which references the input and output actions.

What is Algorithm?

A step-by-step solution,Each step has clear instructions.

E.g:-

Algorithm to add two numbers and print the sum value.

    1.START                                                                                                                        2.Declare 2 integer variables num1,num2                                                                3.calculate num1+num2=sum                                                                                4.print the value sum                                                                                                5.END

What is Pseudocode?

Pseudocode is an artificial and informal language that helps programmers develop algorithms. pseudocode is a text-based details  (algorithmic)design tool.the rules of pseudocode are reasonably straightforward.All  statements ahowing dependency are to be indented.

What is Flowchart?

Flowcharts typically use standard symbols to represent different stages or actions within the chart.
