Learning Style

This course is practical oriented.We will give lots of assignments.

(because practice makes a man perfect )

Memorization will not help you to get a good result.

Copying Code: Strictly prohibited. Will be severely punished if you are caught.

Description of C

General-purpose languageProcedural (= functions + data)Mid-levelRelatively small, simple to learnCross-platform language, single-platform compilers

(unlike Java)Char-based

History Of C

Modern language ALGOL 1960sBCPL -1967, System softwareB -1970, create UNIX OS, Bell LaboratoriesB and BCPL type less C coming from ALGOL, BCPL and B by

Dennis RitchieFurther UNIX was developed by C

Why C?

Prior to C, two broad types of languages: Applications languages

High-level COBOL, etc. Portable but inefficient

Systems languages Low-level Assembly Efficient but not portable

Goal of C: efficient and portable

Why not Java, C++, etc.?

Java is safe and elegant, but slowC++ is unsafe and fast, but highly complexC is unsafe, but succinct and fastC/C++ is still used for:

Systems programming Windows, Unix, etc.

High-perf back-end servers

16

A Simple C Code

#include <stdio.h>

int main()

{

printf(“Welcome to CSE113\n”);

return 0;

}

How to Run

Save a source code with extension “c” or “cpp”. (Ex: first.c)

Compile it and link it Output: first.exe

Run the program.Output of the program:

Welcome to CSE102

Typing Speed (Not related to this course but Important)

Important for every student in CSETry to type in grammatical way – Use 10 fingers

to typeUse software to learn grammatical way of typingSpeed:

Should be at least 30 WPM (Words per minute) Preferable 35+ WPM.

Rewards..Software

Ten Thumbs Typing Software Or, any other Typing tutor software

Puzzle 1: Handshake

It is your first day at CSEPSTU. The teacher (SMZ) suggested that it would be a good idea for each student to meet every other student in the class. The teacher said, "When you meet, please shake hands and introduce yourself by name.“

If there were 14 student in the class, how many total handshakes were there?

Answer: ??

Puzzle 3 - Eggs

Eight eggs look identical except one is lighter. How can you weigh only 2 times on a balance scale to find out which one is lighter?
