build a function in C++that can compare two parameters. This function should return a negative value (the value should be meaningful if possible: otherwise just make sure it's negative) ifthe first parameter is smaller, 0 if they are equal, and a positive value if the first parameter is larger (the value should be meaningful if possible; otherwise make sure it's positive). This function should work with int, char, double, and string types Implement a function template to achieve the goal. After implemented the function template, test it with the following main function to make sure it will return the e int mainO ta; :eeu, return pos (prefer (prefer -32) 0.5)
