Read a 3-character string from input into variable inputString. Declare a Boolean variable isValid and assign isValid with true if inputString only contains alphabetic characters. Otherwise, assign isValid with false. Ex: If the input is hgr, then isValid is assigned with true, so the output is: Valid string Ex: If the input is 3rx, then isValid is assigned with false, so the output is: Invalid string Note: Use getline(cin, inputString) to read the entire line from input into inputString. In C++ please. #include #include #include using namespace std; int main() { string inputString; /* Your code goes here */ if (isValid) { cout << "Valid string" << endl; } else { cout << "Invalid string" << endl; } return 0; }
