1. Understanding the Expression in if:

   Inside the condition of the if statement, we have the expression:

   $$if(a=10)$$

   Notice that a single equal sign ($=$) is used here instead of a double equal sign ($==$). In C++, $=$ is the assignment operator, not the relational equality operator.

2. Evaluation of Assignment:

   The expression $a=10$ assigns the integer value $10$ to the variable $a$. The value of an assignment expression as a whole is the value that gets assigned. Therefore, the expression evaluates directly to:

   $$10$$

3. Boolean Conversion:

   In C++, any non-zero integer value is implicitly converted to a boolean value of true, while $0$ is considered false.

   Since $10\ne 0$, the condition evaluates to true:

   $$\text{Condition: }10\to \text{true}$$

4. Execution of Code Blocks:

   Because the condition is true, the code inside the if block executes, and the else block is completely skipped.

   \text{cout << "Good";}

Thus, the program outputs Good.
