Course learning outcomes 8

Course description

This course aims to introduce students to the basic concepts and principles of programming using a high-level language. Its primary intention is to develop key programming and problem solving skills.

Learning outcomes

At the end of the course, you should be able to ▪ Use a code editor to edit and document source code ▪ Develop algorithms to solve basic to moderately complex

computational problems

▪ Write programs in a high-level language to implement algorithms ▪ Compile, test and debug Java programs High-level Language = JAVA

Course assessment criteria 10

Course assessment

▪ 3hrs Final Examination: 50% ▪ 2hrs Midterm Test: 15% ▪ Lab Tests x 2: 10% ▪ Graded Labs: 20% ▪ Participation: 05% ©https://dilbert.com/ Thou shall NOT miss labs! And Lectures!

Collusion : helping or attempting to help another student commit any act of academic dishonesty including cheating, plagiarism and/or falsification of data and information. Plagiarism : representing the words, ideas and information of another person as one’s own in any academic work. Work must be the student’s original work and in the student’s own words, except for quotations from published and unpublished sources that should be clearly indicated and acknowledged as such.

App development life cycle

Programming 17 ▪ is the process of designing and building an executable computer program for accomplishing a specific computing task. - Wikipedia ▪ A program is a set of instructions, that are written in a language that the computer understands, to perform a specific task. ▪ Need to know what initial tasks a computer can do ▪ Need to learn the computer’s language aka a programming language Machine Language 01001000 01100101 01101100 01101100 01101111 00100000 01010111 01101111 01110010 01101100 01100100 Assembly Language MOV AX,DATA MOV DS,AX LEA DX,MSG MOV AH, INT 21H MOV AH, High-level Language for(int i = 0 ; i < items.length; i++){ System.out.print(items[i]); if (i < items.length - 1 ) System.out.print(", "); } ▪ Understood by the computer ▪ People don’t like it at all ▪ Easily understood by the computer ▪ Has to be converted to machine language ▪ People can live with it ▪ A compromise ▪ Must be converted to machine language ▪ At this point, our solution How about natural language? English? Setswana?

Which high-level Language? 19 ▪ Not all high-level languages are created equal. ▪ Should we all speak English? German? Zulu? French? ▪ Think of programming languages as tools Machine Language Assembly Language High-level Language Hardware BASIC C FORTRAN ALGOL COBOL^ LISP^ C++ (^) JAVA ADA (^) JAVA PYTHON Ease of use C#

Which language? – popularity contest… 20
