Problem

Develop an analogous C++ program which plays with only the single-parameter math library functions described in Figure 6.2 (uploaded pic). Build a table of functions that your program drives through with a for-statement to process a single double-precision real.

Hint #1 Since youre using only the single-parameter math library functions, do not make an entry in your table for either of the 2-parameter functions fmod() and pow()).

Hint #2 Your FUNCTION struct can be a little simpler than the one FunWithFunctionPointers.cpp used because there is no need for the returnsBool field. Why? Because each function-pointer in your table points-to a function that returns a double-precision real result that has only 1 interpretation. For the same reason, the body of your for-statement is also simplerno need for an if/else-statement to select between the different interpretations!

Please post source code with your reply so I can easily copy & paste it into my compiler. Also, please post a screenshot with it compiled. Thank you,
