Week 1

Notes for the first class:

In Visual Studio: Click on Projects - Other Languages, Visual C++ win32 and win32 console application

Application settings - console application and empty project

There are two types of variables: integers and floating points

Integers: long - 4 bytes, short 2, int 4 (or 2 or 8), char 1, long long - 8, pointer 4

Floating Points: double, float, long double

Floating points have precision, which means they are not precise. NEVER compare two floating points for equality. It won't work. THe way to do that is deduct one from the other. If it is 0, they are equal.

operators: assign and return a value, so j= k+2 is the same as writing j = 2; the statement k+2 returns a value of 2 to the variable j.

conditions: !j (turns the variable j into a condition) if j is 0 it will be true (or 1) else it will be false (or 0).

question at end: answer n+= !a[i]; he wanted inside a for loop to only assign the 0's to variable n.
