Question

A. Determine whether the following is a valid beginning of a function definition vold PrintValues(double x, int y) Select one: a. Valid b. Invalid B. The following is an example of a function stub: int CountofAlpha(string input) ( int count = 0; int i = 0; for(i = 0; i input. length(); ++i) { if (isalpha(input.at(i)) ++count; return count; Select one: a. True b. False C. Which statement contains a common error or mistake with functions? double AreaOfCircle(double radius) const double pi = 3.14159265; double area 0.0; double temp = 0.0; temp = pow(radius, 2); area = pi * temp; return radius; Select one: a. const double pi 3.14159265; b. temp pow(radius, 2); c. return radius; d. No errors or mistakes.

Explanation / Answer

A: TRUE, it is a valid declaration of a function "ReturnType functionName(Parameter, Parameter,..)".

B: FALSE, Stubs are basically small or empty functions executes real quick and which returns a value, where as in the example they is a for loop which will take more time if no of iterations increases.

C: return radius; insted of returning the areaOfCircle as mentioned in the Method name it is retuning radius which is same value passed as parameter.

D: 2. There are 2 out put statements(cout<<) in the PrintName() function.

E: TRUE, A function can be overloaded many times.
