C Correct answer
Explanation

In C/C++, 7/9 is integer division. Both operands are integers, so the result is 0 (truncated), not 0.777. Then 0*9 = 0. Floating-point division would require at least one float operand (e.g., 7.0/9 or 7/(float)9).

AI explanation

To evaluate the expression 7/9 * 9 in C and C++, we need to consider the data types involved.

By default, when dividing two integers in C and C++, the result will be an integer, which means the decimal part will be truncated.

Let's evaluate the expression step by step:

7/9 = 0 (since both 7 and 9 are integers, the result will be an integer and the decimal part is truncated)

0 * 9 = 0 (0 multiplied by any number is 0)

Therefore, the result of the expression 7/9 * 9 in C and C++ is 0.

Hence, the correct answer is option C.
