2.2.1 Programming fundamentals Flashcards
What is a variable?
Value in your program that can change when program is running
What is a constant?
Value in your program that cannot change when program is running
What is a construct?
The building blocks of a program?
What are the 3 constructs?
Sequence
Selection (if statement)
Iteration (loop)
What is a sequence?
When code can run in the order that is written
What is an example of a sequence code?
1) A=5
2) B=6
3) Ans = A+B
4) print(Ans)
What is selection?
(if statement)
When code can jump to a different section based on location
What is an example of a selection code?
1) A=5
2) B=6
3) if A>B
4) print(A)
5) else
6) print(B)
What is iteration?
(loop)
When code repeats until condition is met
What are the two types of iteration loops?
Count controlled loop (for loop)
Condition controlled loop (while loop)
What is a count controlled loop?
(for loop)
Set a counter and you iterate that many times
What is an example of a count controlled loop?
for (i) in range (0,10) or (10)
print (name)
print(str(i)+name)
How can you count in twos in a count controlled loop?
for (i) in range (0,51,2):
print(i)
How can you count down in twos in a count controlled loop?
for (i) in range (50,-2,-2)
print(i)
How can you make your print go across the page in a count controlled loop?
for (i) in range (0,51)
print(1 , end = “ “)
