Iteration Practice

Front

Consider the following code segment. What value is stored in the variable count as a result of executing the code segment?

Back

1

Front

Consider the following two code segments. Code segment II is a revision of code segment I in which the loop header has been changed. Which of the following best explains how the output changes from code segment I to code segment II?

Back

The code segments print the same values but in a different order, because code segment I iterates from 1 to 5 and code segment II iterates from 5 to 1.

Front

Consider the following code segment. What will be the value of count as a result of executing the code segment? Options: 100, 101, 160, 161, 321

Back

161

Front

Consider the following method. Which of the following best describes the value returned from a call to doWhat? Options: num, The sum of all integers between 1 and num, inclusive, The sum of all even integers between 1 and num, inclusive, The sum of all odd integers between 1 and num, inclusive, No value is returned because of an infinite loop.

Back

The sum of all odd integers between 1 and num, inclusive

Front

What value is returned as a result of the call numCalc(8)? Options: 1, 3, 5, 8, 13

Back

13

Front

Consider the following two code segments. Assume that the int variables m and n have been properly declared and initialized and are both greater than 0. Assume that the initial values of m and n are the same in code segment I as they are in code segment II. Which of the following correctly compares the number of times that "A" and "B" are printed when each code segment is executed?

Back

"A" is printed m more times than "B".

Front

Which of the following code segments produces the output "987654321"?

Back

Front

Which of the following best describes the conditions under which methodOne and methodTwo return the same value? When a and b are both even, When a and b are both odd, When a is even and b is odd, When a % b is equal to zero, When a % b is equal to one

Back

When a % b is equal to zero

Front

Consider the following code segments. Code segment 2 is a revision of code segment 1 in which the loop increment has been changed. Code segment 1 prints the sum of the integers from 1 through 30, inclusive. Which of the following best explains how the output changes from code segment 1 to code segment 2?

Back

Code segment 2 will print the sum of only the odd integers from 1 through 30, inclusive because it starts k at one, increments k by twos, and terminates when k exceeds 30.
