Unlike Java, the C++ string class has no toLowerCase member function. Write a regular function to Lowercase. You may use any loop you like. You may also use the character functions in the header. Complete the following file: main.cpp #include #include using namespace std; 1 2 3 4 5 6 7 8 9 10 11 12 string toLowerCase(const string& s) { string result; // Add your loop here return result; Submit
