What will be the output of the following C++ code? #include <iostr...

Explanation:

- The code first declares two integer variables x and y.
- It then assigns the value 5 to x.
- In the line `y = ++x * ++x;`, both x values are incremented before the multiplication operation is performed.
- After the increment, x becomes 6, so the expression becomes 6 * 6 which equals 36. The value of x is 6 and y is 36.
- The first output will be `636`.
- Then x is reset to 5 and the line `y = x++ * ++x;` is executed.
- In this line, the left operand x is post-incremented after the multiplication operation is performed with the pre-incremented right operand x.
- After the increment, x becomes 7, so the expression becomes 5 * 7 which equals 35. The value of x is 7 and y is 35.
- The second output will be `735`.

Therefore, the output of the code will be `636735`.
