Unit 3 Sections 8 and 10
During this lesson sections 5 and 7 will discuss lists and iteration
Notes:
Nested Conditionals
- Nested conditional statements consist of conditional statements within conditional statements
- they're nested one inside the other
- An else if inside of another else if
- Can be used for a varying amount of "else if statements." The first if statement can represent if two coditions are true. The first else if can represent if only one or the other is true. The last else if represents if neither of the conditions are true.
Take aways
- Learn how to determine the result of nested condtional statements
- Nested conditional statements consist of conditional statements within conditional statements
Essential Knowledge
- Conditional statements ("if" statements) affect the sequential flow of control by executing different statements based on the value of a Boolean expression.
-
In which the code in block of statements is executed if the Boolean expression condition evaluates to true; no action is taken if condition evaluates to false
-
Conditionals allow for the expression of algorithms that utilize selection without a programming language.
- Writing conditional statements is key to computer science.
-
Determine the result of conditional statements
-
The defention of a Boolean is a denoting a system of algebraic notation used to represent logical propositions, especially in computing and electronics.
- A boolean expresions are either true or false.
- Testing if two numbers or variables are equal is a common example.
- For example: The sky is blue = True
Hacks
- Explain in your own words what each logical operator does
- AND: used to check if conditions are met
- OR: used to check if one condition is met
- NOT: it displays the opposite of whatever the data is. Mainly used for true/false, and does not effect the variable.
- Code your own scenario that makes sense for each logical operator
