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 // CS 105 // Section 042 #include <iostream> using namespace std; int main() { cout << “Hello World!!” << endl; return (0); }
