// The program takes a string and interprets it firstly. The first thing which
// the program does is checks whether the string is either
// a) Empty
// b) Too short
// Should it be either of these two, it returns the values -1 and -2
// respectively.
// After that, the program takes the string defined and turns it around
// with each word being inverted. This is done through the function
// reversePrint. The output value is a reversed string with each word
// being reversed separately, as well as starting letters being capitalised
// and every other letter being lower-case.
