What’s Programming What is computer programming? What is an algorithm? Interpretation of a task or algorithm in a computer language. What is an algorithm? A set of instructions for accomplishing a task. Input and Output

What’s Programming How about preparing salad? Steps: Clean and cut vegetables Put sauce & cheese Stir

What’s Programming -An example The algorithm for sorting three integers in ascending order, given 20, 5, 8. Steps: 5, 8, 20 To determine the concrete steps involved in solving a problem, we may Logically represent the problem Implement the logic in computer languages (c, c++, java, python, perl…) Given a thousand integers?

Why Programming Manually operating – not possible Google search engine (Searching in a File)

Basic Components of a Computer CPU – central processing unit RAM – random access memory Computer data storage Integrated circuits – randomly access with constant time Permanent memory – hard disk Computer peripheral – mouse, keyboard

Programming Platform For omega access, each student that needs to have access to it will need to contact the help desk and request it. The best way is to call them at 817-272-2208 and ask to have omega access added to your NetID account.

First Example

First Example # include <stdio.h> int main( ) /* a … */ Tell compiler to include the information included in studio.h int main( ) A function name C programming consists of one or more functions (basic modules) Parenthesis identify a function Similar to the function defined in math Arguments and return /* a … */ Enclose comments (block), “//” – single line Intended for the reader and ignored by the compiler

First Example { - the beginning of the function body (statements separated by “;”) int num; A declaration statement num is an identifier Declare a variable before using it Traditionally, declare it at the beginning Lowercase letters, uppercase letters, digits, the underscore First character must be a letter or an underscore Not key words

First Example num = 1; printf(“ ”) \n an assignment statement Set space in memory Reassign later printf(“ ”) Part of the standard C library, a function \n Start a new line

First Example %d return - a return statement of a function Placeholder/format specifier - where and in what form to print return - a return statement of a function } – the end of the function

A “Good” Program There are different criteria by which one program may be considered better than another. Some examples are: Readability – collaborative work Maintainability – self-updated Scalability – large-scale data set Performance (e.g., how fast it runs or how much memory it uses)
