Understanding the Comma Operator in C

1. Break Down the Problem

   • The code snippet provided uses the comma operator in C programming.
   • We need to determine the value assigned to variable a when the line a = (1, 2, 3); is executed.

2. Relevant Concepts

   • In C, the comma operator evaluates its first operand (in this case, 1), discards the result, then evaluates its second operand (2), discards that result as well, and finally evaluates the third operand (3), which becomes the result of the expression.

3. Analysis and Detail

   • The expression (1, 2, 3) means:
     • Evaluate 1 → discarded
     • Evaluate 2 → discarded
     • Evaluate 3 → this is the final result.
   • Therefore, the value assigned to a is 3.

4. Verify and Summarize

   • After evaluating the expression using the comma operator, we confirm that the final value assigned to a is indeed 3.

Final Answer

The value of a is 3.
