Algorithm Flashcards
What is an algorithm?
A set of instruction to perform a specific task.
It is a well-defined step by step solution.
Algorithm.
What are the 2 ways of representing an algorithm?
- Flowcharting
- Pseudocode
It is a variable declaration that is placed in an oval.
Terminal box.
It represents the beginning/end of a code.
Terminal box.
More than 2 terminal boxes can exist in a code.
False.
It is used to connect symbols and indicate the flow of logic.
Flowlines.
A variable declaration in a hexagon.
Initialization box.
What is the purpose of an initialization box?
To declare a beginning value.
A variable declaration in the shape of a parallelogram.
Input/output box.
The input/output box allows…
reading and printing of the data.
A variable declaration in the shape of a rectangle.
Processing box.
The processing box operates….
arithmetic and data manipulation.
A variable declaration in the shape of a diamond.
Decision box.
This operates logic and comparisons.
Decision box.
4 examples of words used in a decision box.
- Yes
- No
- True
- False
A variable declaration similar to a process box.
Predefined process box.
A predefined process box is a marker…
for another process formally defined elsewhere.
A variable declaration in the shape of a circle.
On-page connector.
An off-page connector allows flowcharts to connect on the same page.
False. On-page connector.
A variable declaration in the shape of an upside-down pentagon.
Off-page connector.
What is the purpose of an off-page connector?
To connect a flowchart to another page.
“Pseudo” means…
False.
A pseudocode describes an algorithm using a combination of…
natural and programming language.
A pseudocode can be run.
False.
Flowcharts and pseudocodes are read according to…
sequential operation.
A sequential operation has no…
conditional or iterative processing.
Sequential operation is read from left to right and bottom to top.
False.
A conditional operation is a step where…
a decision must be made.
This operation asks questions and chooses actions based on the available options.
Conditional operation.
What does modulum get?
The remainder.
How to structure using the modulum (mod) function?
“NUM mod 2 = 0”.
The remainder is 0.
This operation is more convenient for multiple processes.
Case strcuture operation.
This case is usually included in case structure operation.
“Default”.
Repetition operation uses a _ mechanism which causes a _ of statements based on _ set.
loop, repetition, conditions
When a loop body is executed, then…
there will be a change in value of at least one variable.
Most loop mechanisms have this effect.
Cumulative effect.
What is a counter?
A variable that determines the number of loops.
What is an accumulator?
A variable used to store results of an iteration.
It acts as a storage for the result.
Accumulator.
This operation depicts a sub-routine/process.
Function call operation
This is used to determine the variables needed (i.e., input, output, etc.).
Problem analysis.
