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

How about preparing salad?
◦ Steps:
 Clean and cut vegetables
 Put sauce & cheese
 Stir

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

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.

◦ 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


{ - 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

◦ Set space in memory
◦ Reassign later



%d
◦ Placeholder/format specifier - where and in what
form to print

return - a return statement of a function
} – the end of the function

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)
