You forgot to write TestClass:: as shown below:

void TestClass::set(string x)
   //^^^^^^^^^^^this

void TestClass::print(int x)
   //^^^^^^^^^^^this

That 5 is necessary so that compiler can know that 4 set and print are member functions of class TestClass. And 3 once you write it, making them member functions, they 2 can acess the private members of the class.

Also, without 1 TestClass::, set and print function would become free functions.

Use

void TestClass::set(string x){

and

void TestClass::print(int x){

Score: 3

In your .cpp file, you need to make the set 2 and print member functions explicitly part 1 of the class, like:

void TestClass::set(string x){
    hi = x;
}

void TestClass::print(int x){
    if(x == 2)
        cout << hi << " x = two\n";
    else if(x < -10)
        cout << hi << " x < -10\n";
    else if(x >= 10)
        cout << hi << " x >= 10\n";
    else
        cout << hi << " x = " << x << endl;
}

Score: 2

You don't scope resolve your print and set functions 1 with the class name.

void TestClass::set(string x){
    hi = x;
}

void TestClass::print(int x){
    if(x == 2)
        cout << hi << " x = two\n";
    else if(x < -10)
        cout << hi << " x < -10\n";
    else if(x >= 10)
        cout << hi << " x >= 10\n";
    else
        cout << hi << " x = " << x << endl;
}

Score: 1

say

void TestClass::set(string x){

instead of

void set(string x){

same for print(). You declared 2 them as global functions instead of member 1 functions of TestClass.

Score: 0

Your methods are not defined as methods 2 of the class. Try using TestClass::set and 1 TestClass::print.
