The two header files a.h and b.h both have a prototype for a single function. Both have at least two mistakes. Fix the mistakes so that the tester program works correctly. Complete the following files: a.h 1 #include 2 #include "b.h" 3 /** 4 Converts a character into the corresponding string form. 5 For example, calling charToString('Q') returns the string "Q". 6 @param c the character to convert. 7 @return the string form of the character. 8 *11 9 string charToString(char c); 10 b.h 1 2 3 4 5 6 7 8 9 #include #include "a.h" /** Returns a string version of the bool argument. @param b the Boolean value to convert @return "true" or "false" */ string boolToString(bool b); Submit Use the following file: Tester2.cpp #include using namespace std; #include "a.h" main() { cout
