Question
Which of the below statements is equivalent to add += add
?
add = add
add = add + add
add = add + 1
add = add + add + 1
Solution
To determine which of the statements is equivalent to "add", we can break down each option and analyze them step by step:
-
add This statement is not equivalent to "add" because it simply assigns the value of $add to itself, without performing any addition.
-
add + add += add and add, which is essentially doubling the value of $add.
-
add + 1 This statement is also not equivalent to "add". It assigns the value of add, which increments $add by 1.
-
add + add += add, add, effectively adding the value of $add to itself and then adding 1.
Therefore, the statement that is equivalent to "add" is "add + $add + 1".
