  4. 4. Programming We first define the word “programming”, it is a computer language programmers use to develop applications, scripts, or other set of instructions for a computer to execute. programming is instructing a computer to do something for you with the help of a programming language. The role of a programming language can be described in two ways: Technical: It is a means for instructing a Computer to perform Tasks Conceptual: It is a framework within which we organize our ideas about things and processes. http://eglobiotraining.com/
  5. 5. As an individual, I have learned that programming is a very broad because it composes many scripts, applications and can be used to run a program that has been part of the programming language. A programming language should both provide means to describe primitive data and procedures and means to combine and abstract those into more complex ones. http://eglobiotraining.com/
  6. 6.  The distinction between data and procedures is not that clear cut. In many programming languages, procedures can be passed as data (to be applied to ``real'' data) and sometimes processed like ``ordinary'' data. Conversely ``ordinary'' data can be turned into procedures by an evaluation mechanism. http://eglobiotraining.com/
  7. 7.  If we know how to write a C expression that is equivalent of a question such as “Is resting the value of expression to select a course of action. In C, the statement is the primary selection control structure  Me: it’s hard to write c expression. So, I just copy and paste it into internet.  A programming language is an artificial language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely. http://eglobiotraining.com/
  8. 8. At first, programming is confusing because you have so much to understand about codes that will enable to run a program. Programming has applications and program development, the best example for this is the Internet browser… Programming is a creative process done by programmers to instruct a computer on how to do a task. Programming languages let you use them in different ways, e.g adding numbers, etc… or storing data on disk for later retrieval. http://eglobiotraining.com/
  9. 9. You have to consider languages to run or write your own program, most demanded language in programming is the DEV C++ (a full-featured Integrated Development Environment (IDE)). C++ is one of the most used programming languages in the world. Also known as "C with Classes". New to programming or thinking about it? It might surprise you to know that there are many programmers who program just for fun and it can lead to a job. http://eglobiotraining.com/
  10. 10. - A switch, case, select or inspect statement is a type of selection control mechanism that exists in most imperative programming languages such as Pascal, Ada, C/C++, C#, Java, and so on. It is also included in several other types of languages. Its purpose is to allow the value of a variable or expression to control the flow of program execution via a multiway branch (or "goto", one of several labels). The Main Reason using switch case : - To improve clarity, by reducing otherwise repetitive coding, and (if the heuristics permit) also offering the potential for faster execution through easier compiler optimization in many cases. http://eglobiotraining.com/
  11. 11. 1. The If – else Statement -The if statement allows the programmer to make decisions within a program. - The general format of an if statement is: If (expression) statement -Where expression represents a relational, equality, or logical expression ( conditional expression) . http://eglobiotraining.com/
  12. 12. If statement (two alternatives) Form: If (condition) Note: if condition evaluates to true, then statement is statement; executed and statement is skipped; otherwise, statement is else skipped and statement is executed statement; If statement (One-Alternatives) Form: If (condition) Note: if condition evaluates to true, then statement is statement; executed and statement is skipped Format of the if statement - All if statement examples in this text indent statements. The word else Is typed without indention on a separate line. The format of the if statement makes its meaning apparent and is used solely to improve program readability; The format makes no difference to the computer http://eglobiotraining.com/
  13. 13.  There may be a situation when you need to execute a block of code several number of times. In general statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.  Programming languages provide various control structures that allow for more complicated execution paths.  A loop statement allows us to execute a statement or group of statements multiple times and following is the general from of a loop statement in most of the programming languages: http://eglobiotraining.com/
  14. 14.  1. Open Dev C++  2. Click File and choose New  3. Post your Statements  4. after you post your statement  5. Save it .choose file and save or  6. click f9 or you can see it shaped like a square http://eglobiotraining.com/

  16. 16. Link: http://gd.tuwien.ac.at/languages/c/programming- bbrown/c_028.htm The above program uses a switch statement to validate and select upon the users input choice, simulating a simple menu of choices. http://eglobiotraining.com/
  17. 17. When it compiles and run, this will be it look . The C expression that was type it on Dev C++ The words are “enter in two number  24” http://eglobiotraining.com/
  18. 18. Link: http://www.morrowland.com/apron/tutorials /cpp/cpp_switch_case/index.php Example of Switch Case Statement , you Will see the statement on the link that you see in this slide. http://eglobiotraining.com/
  19. 19. After I compile it and run it, the statement is now like this. As you Can see after you answer the 1st question the next question appear And after you finish all the question the box will disappear. It means finish. http://eglobiotraining.com/
  20. 20. Link: http://www.morrowland.com/ap ron/tutorials/cpp/cpp_if_else/in dex.php Function and target of Programming language : A computer programming language is a language. used to write computer programs, which involve a computer performing some kind of computation or algorithm and possibly control external devices such as printers , disk drives , robots, and so on. http://eglobiotraining.com/
  21. 21. When the statement was done this will it be look like. I got this from the URL . The URL was posted on the previous slide http://eglobiotraining.com/
  22. 22. http://msdn.microsoft.com/en-us/library/66k51h7a(v=vs.80).aspx Did You Know? The first programming languages predate the modern computer. The 19th century saw the invention of "programmable" looms a nd player piano scrolls, both of which implemented examples ofdomain-specific languages. http://eglobiotraining.com/
  23. 23. Did You Know ? All programming languages have some primitive building blocks for the description of data and the processes or transformations applied to them(like the addition of two numbers or the selection of an item from a collection). These primitives are defined by syntactic and semantic rules which describe their structure and meaning respectively. http://eglobiotraining.com/

  27. 27. Looping Statements - Loops execute a block of code a specified number of times, or while a specified condition is true. - in PHP, the following looping statements are used: *The while Loop * The Do… While Loop * The For Loop *The Foreach Loop *Break and continue statement http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
  28. 28. While structure is another type of loop statements, where the condition is checked at first, the iteration will not stop even if the value changes while executing statements. Form: While(condition) { code to be executed; } http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
  29. 29.  Do while statement is same as the while statement , the only difference is that it evaluates the expression at the end. Form: do { code to be executed; } while (condition): http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
  30. 30.  The for loop is used when you know in advance how many times the script should run.  Be for statement takes three expressions inside its parentheses seperated by semi-colons. When the for loop executes, the following occurs:  The initializing expression is executed. This expression usually initializes oneor more loop counter, but the syntax allow expression any degree of complexity.  The condition expression is evaluated. Of the value of condition is true, the loop statements execute. If the value of condition is false, the for loop terminates.  http://www.slideshare.net/ilakkiya/looping- statement http://eglobiotraining.com/
  31. 31. Form: for {initialization; condition: increment ) { code to be executed } http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
  32. 32.  For Each structure is a loop structure used for arrays Form: foreach(array as value) { code to be executed } Foreach (array as key => value) { code to be executed } http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
  33. 33.  Break ends the execution of the for, for each, while, do-while or switch statement. Form: * Break ( optional numeric argument) http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
  34. 34.  “Continue” is used to skip the current loop iteration and continue with the next iteration of the loop. But “Break” is to exit from the whole loop. Form: * Break ( optional numeric argument) http://www.slideshare.net/ilakkiya/looping-statement http://eglobiotraining.com/
