Given a variable named result, which operation will be executed first?result = total / count * (max - offset);
Question
Given a variable named result
, which operation will be executed first?
result = total / count * (max - offset);
Solution
Break Down the Problem
- Identify the components of the expression:
- Variables:
result
,total
,count
,max
,offset
- Operations: Division, multiplication, and subtraction.
- Variables:
Relevant Concepts
- Understand operator precedence in programming:
- Parentheses
()
have the highest precedence, followed by multiplication*
and division/
which have the same precedence (evaluated from left to right).
- Parentheses
Analysis and Detail
- Analyze the expression step by step:
- The operation inside the parentheses
(max - offset)
will be executed first because it is given the highest precedence. - Next,
total / count
is evaluated since both division and multiplication have the same precedence — they are executed from left to right. - Finally, the multiplication of the result from
total / count
with the result from(max - offset)
will be calculated.
- The operation inside the parentheses
Verify and Summarize
- Verify the order of operations:
- First:
- Second:
- Third:
Final Answer
The operation executed first in the expression result = total / count * (max - offset);
is the subtraction inside the parentheses: .
