case | a block of code in a switch statement
catch | handles exceptions from throw
char | declare a character variable
class | declare a class
compl | alternative to ~ operator

dynamic_cast | perform runtime casts
else | alternate case for an if statement
enum | create enumeration types
explicit | only use constructors when they exactly match
export | allows template definitions to be separated from their declarations
extern | tell the compiler about variables defined elsewhere
false | a constant representing the boolean false value
float | declare a floating-point variable
for | looping construct
