| < <= > >= | 1 |
| != == | 2 |

| Expression | What It Evaluates To |
| (exp1 && exp2) | True (1) only if both exp1 and exp2 are true; false (0) otherwise |
| (exp1 || exp2) | True (1) if either exp1 or exp2 is true; false (0) only if both are false |
| (!exp1) | False (0) if exp1 is true; true (1) if exp1 is false |
Truth Table
| Op1 | Op2 | && (And) | || (Or) | ! (Not) | ^ (XOR) |
| TRUE | TRUE | TRUE | TRUE | FALSE | FALSE |
| FALSE | TRUE | FALSE | TRUE | TRUE | TRUE |
| TRUE | FALSE | FALSE | TRUE | FALSE | TRUE |

Compound Assignment Operators:
C compound assignment operators provide a shorthand method for combining a binary mathematical operation
with an assignment operation
Assignment Operators: +=, -=, *=, /=, %=, <<=, >>=, &=, |=, ^=.
Ex. x = x + 5;
Using a compound assignment operator, which you can think of as a shorthand method of assignment, you would
write
x += 5;
