1. The code shows a range-based for-loop going over the elements of the donations std::vector and performing the code block associated with it. Loops run their associated code blocks 0 or more times depending on the condition. We use the term iteration to refer to one of the times the code block runs. How many iterations were performed over the donations std::vector? 2. We see the donation variable's value change in every iteration. Where do you think these values were taken from? Place a check (✔) beside your answer. a. Elements of the donations std::vector b. Randomly generated values c. Default values of the double data type 3. Why do you think we declare the donation variable with a double type? Place a check (✔) beside your answer. a. doubles can store any value that a std::vector might contain b. The std::vector contains elements with a double data type c. std::vectors contain doubles by default 4. In what order are donations' elements assigned to donation as the range-based loop iterates? Place a check (✔) beside your answer. a. donation takes in values randomly b. donation takes in values from smallest to largest c. donation takes in the values sequentially (index 0, 1, ...)

Question
Transcribed Image Text:1. The code shows a range-based for-loop going over
the elements of the donations std::vector and performing
the code block associated with it. Loops run their
associated code blocks 0 or more times depending on
the condition. We use the term iteration to refer to one of
the times the code block runs. How many iterations were
performed over the donations std::vector?
2. We see the donation variable's value change in every
iteration. Where do you think these values were taken
from? Place a check (✔) beside your answer.
a. Elements of the donations std::vector
b. Randomly generated values
c. Default values of the double data type
3. Why do you think we declare the donation variable
with a double type? Place a check (✔) beside your
answer.
a. doubles can store any value that a std::vector
might contain
b. The std::vector contains elements with a double
data type
c. std::vectors contain doubles by default
4. In what order are donations' elements assigned to
donation as the range-based loop iterates? Place a
check (✔) beside your answer.
a. donation takes in values randomly
b. donation takes in values from smallest to largest
c. donation takes in the values sequentially (index 0,
1, ...)
