It looks like you are defining functions inside main(). In this case the data.enter() and data.disp(). These functions need to be outside main:

class Project
{
   public:
   void enter();
};
void Project::enter()
{
   //function code goes here
}
 
int main()
{
    Project data;
    data.enter();
}
