I really need help on these problems. I have no idea on how to do it. C++
12) Show the new layout for a program using functions (but not necessarily libraries). (i.e. Where's main? The #includes? Etc.) (Thought-provoker: Where would inline functions go?) 4) Write a function to round a number (specified by the caller) to the nearest value at a certain decimal place. The decimal place should be the one's place by default. return the number resulting from the rounding to the caller. be potentially useful to your caller?) floor(num/place+.5)*place
