To avoid using functions
What are the three basic types of control structures?
Sequence, Selection, Iteration
Input, Output, Processing

What does it mean that the sequential control structure is the default?
It means that this is the structure the compiler and interpreter will automatically follow.
It means that instructions are executed in reverse order.
It means that instructions are executed randomly.
It means that instructions are executed based on user input.
How does the computer decide which path to follow in a selection control structure?
By evaluating a condition
By random choice
By user input
By following a fixed sequence

What are some of the benefits of using a loop?
It saves time for the programmer, reduces number of lines of code needed, keeps the code clean and to the point.
It makes the code run slower and more complex.
It increases the chances of errors in the code.
It requires more memory to execute.
When is a For loop used?

Conditional statements are used when:
