Give the function prototype (without parameter names) for each of the following:

Question

a) Function hypotenuse that takes two double-precision, floating-point arguments, side1 and side2, and returns a double-precision, floating-point result.
b) Function smallest that takes three integers, x, y and z, and returns an integer.
c) Function instructions that does not receive any arguments and does not return a value. [Note: Such functions are commonly used to display instructions to a user.]
d) Function intToDouble that takes an integer argument, number, and returns a double precision, floating-point result.

Answer 1

a) double hypotenuse( double, double );
b) int smallest( int, int, int );
c) void instructions();
d) double intToDouble( int );
