Please write a C++ program based on the following instructions. Thank you!!

roblem description Write the following functions as prototyped below. Do not alter the function signatures. Demonstrate each function using literal strings defined in your client program (e.g., don't prompt the user for test inputs) /// Returns a copy of the string with its first character capitalized //I and the rest lowercased /// Example: capitalize("hELLO WORLD") returns "Hello world std::string capitalize(const std::string&str) /// Returns a copy of the string centered in a string of length width.. /// Padding is done using the specified 'fillchar' (default is an ASCII space). /// The original string is returned if 'width' is less than or equal to the /// string's length. std:: string center(const std: : string& str, size_t width, char fiuchar- '); /// Returns a copy of the string left justified in a string of length width". /// Padding is done using the specified 'fillchar (default is an ASCII space) /// The original string is returned if 'width' is less than or equal to /// the string's length.
