Create a function in C++ language called rev_str() that reverses a string.Overload rev_str() so it can be called with either one character array or two.When it is called with one string, have that one string contain the reversal.When it is called with two strings, return the reversed string in second argument.For example
char s1[80], s2[80];
strcpy (s1, "hello");
rev_str(s1, s2; //reversed string goes in s2, s1 untouched
rev_str(s1); //reversed string is returned in s1
