Course Philosophy

• Computer Science Side– Problem Solving– Logical Thought– Programming in C++

• “Real World” Side– Human Nature– Corporate World– Surviving during and after College

Problem Solving

• Arrange a Deck of Cards by Suit and Rank

• How Would You Do This?

• How Would You Tell a Child to Do This?

• How Would You Tell a Computer to Do This?

Problem Solving

• CS 105 Develops Logic Skills to Solve Problems by Writing a Program

• A Program is a Problem Solving Tool

• Computers Follow Instructions Given to Them

• Computers Do Not Have “Intuition”

• Computers Do Not Make Decisions “on Their Own”

Why Use a Program?

• Computers Perform Tasks Many Times Faster than a Person

• Computers Are More Consistent than a Person

• Computers Can Work 24-7

Terminology

• Source Code: the Original Problem-Solving, Logical Solution Written in a Programming Language (e.g. C++)

• Compiling: the Action of Turning the Source Code into a Format the Computer Can Use

• Linking: the Action of Bringing in Already Written Code (Libraries) for Use in a New Program

• Executable: the Result of Compiling and Linking a Source Program; the “.exe” file that the Computer Can Run

C++ Required Elements

• Every C++ Program Must Have:

int

main()

{

}

Your First Program// Jon Hanrath

// CS105

// Section 042

#include <iostream>

using namespace std;

int

main()

{

cout << “Hello World!!” << endl;

return (0);

}
