high-level language	allows to write precise instructions in a human-readable form	human-readable
syntax	vocabulary and grammar of a language	vocabulary
variables	1. provide temporary storage during the execution of a program. 2. placeholder used to store values. a variable has a name and a data type.	temporary
constants	data fields or local variables whose value cannot change	fields or variables

if statement	will execute only if boolean expression evaluates to true	will execute if....
switch statement	allows multi-way branching. Can simplify combinations of if-else statements	allows...
(switch) case statement	match the switch expression with a constant. Both must be of the same data type.
(switch) default statement	executes when the switch expression doesn't match with any of the case statements

what are the parts of a loop?	initializer loop test termination expression	in, lt, te
do-while loop	repeatedly executes a block of statements until a specified Boolean expression evaluates to false. the do-while loop test the condition at the bottom of the loop.
while vs do-while	while executea 0 or more times. do-while executea 1 or more times.
for loop	combines the three elements of an iteration into a more readable code.	combines
foreach loop	useful for iterating through the elements of a collection
