Class divide header and definition file
I have to divide it. This code works. However, each class definition in its own header file (.h), each class member function definitions in its own source file (.C), and the program application in its own source file. I don't know how to do that. It is not fully connected.
I get the following error:

Its as simple as this:

void display_sp(int); //function to display account details given by user
void display_all(); //function to display all account details
void deposit_withdraw(int, int); // function to desposit/withdraw amount for given account
// Main function
int main()
{
