What happens if a value-returning function with the prototype:

float Average( int, int, int);

is called by using the following statement? (alpha and beta are int variables.)

average(alpha, 34, beta);

a) The function is executed, and the function value is discarded.

b) The function is not executed, and the program halts with a run-time error message.

c) The compiler issues a syntax error message.

d) The function is executed, and the function value is assigned to alpha.
