Question:

What does the condition in this for loop mean? Assume that the variables are already called and initialized. int[] array = new int[] {1, 2, 3}; for (int c : array) { //do something }

Bresia P.
Answer:

This is a for-each loop which takes the left value (in our case, this would be c) and then sets it to each right value (which is array). For instance, array contains [1, 2, 3], so c would be 1 in the first iteration, 2 in the second iteration, and so on.

Question:

Evaluate |3 - 6(2 - 11)| - |6 - 12|

Bresia P.
Answer:

According to the order of operations, inner brackets are solved first. Hence: = |3 - 6(-9)| - |6 - 12| According to the order of operations, multiplication within absolute value signs are solved next. You can think of the multiplication as brackets as well. Hence = |3 - (-54)| - |6 - 12| = |3 + 54| - |6 - 12| = |57| - |-6| = 57 - 6 = 51
