A 3-character string, userString, is read from input. Replace the first character in userString with '=' if the first character is alphabetic. Replace the second character in userString with '$' if the second character is alphabetic. If neither condition is true, userString is not changed. Ex: If the input is gwv, then the output is: =$v #include #include #include using namespace std; int main() {    string userString;    getline(cin, userString);        /* Your code goes here */        cout << userString << endl;    return 0; }
