Practice!!! Test code (debug)

To succeed in this course

What is computer programming?◦ 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

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?

What’s Programming-An example

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

Why Programming

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

Basic Components of a Computer

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.

Programming Platform

First Example

# include <stdio.h>◦ 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;◦ 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◦ Placeholder/format specifier - where and in what

form to print return - a return statement of a function } – the end of the function

First Example

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)

A “Good” Program
