Question
What will be the final values stored inside variables 'a' and 'b' when the following C# code snippet is executed?
int a, b;
a = (b = 10) + 5;
Solution
To determine the final values stored inside variables 'a' and 'b' after executing the given C# code snippet, let's analyze the code step-by-step.
1. Break Down the Problem
We have the following code:
int a, b;
a = (b = 10) + 5;
2. Relevant Concepts
- Assignment in C#: In C#, the assignment operator
=
is evaluated from right to left. - The parentheses change the order of operations.
3. Analysis and Detail
- The expression
(b = 10)
is evaluated first. This meansb
is assigned the value10
. - The value of the expression
(b = 10)
is10
, so now we can substitute it back into the equation fora
. The equation becomes: - Now, we perform the addition:
4. Verify and Summarize
After executing the above assignments:
b
will hold the value10
.a
will hold the value15
.
Final Answer
- The final value of variable
a
is 15. - The final value of variable
b
is 10.
