Find the output of the following #include<stdio.h> int main() { int x = 5, y =…

The core of this problem lies in the expression: x = (x = x + y) - (y = x - y);. This is an example of an expression that technically results in undefined behavior in standard C because it modifies the same variable multiple times without a sequence point. However, most modern compilers (and competitive exam environments) evaluate it using a specific mathematical sequence.

1. Initial Values: x = 5, y = 9.

2. Evaluating the Parentheses:

   • First sub-expression (x = x + y): x becomes 5 + 9 = 14. The value of this sub-expression is 14.

   • Second sub-expression (y = x - y): Now, x is 14. So, y becomes 14 - 9 = 5. The value of this sub-expression is 5.

3. Final Assignment for x:

   • x = (14) - (5) = 9.

4. Final Result: x = 9, y = 5.
