Answer

Explanation / Answer

Ans:

Incorrect: A function can return many values to the calling program.

True statement :There are two different data storage locations for the variables and the compiler makes no connection between the two variables.

Valid function call: p = something (p, m);

y = abs(x); => y contains the absolute value of the value in x

it is passed as a reference parameter.
