Yes. But first you need to post the code you have tried to solve the problem. We are not a program manufacturer.

this is my program codes:

#include <iostream>
#include <string>
#include <stack>
#include <cctype>


using namespace std;

// The following defns should go into a .h file

#define PrintWrtSurname "ps"
#define PrintWrtId "pi"
#define AddStudent "i"
#define DeleteStudent "d"
#define Quit "q"

void editStudentList(/* StudentList&*/)
{
	string command;

	cout << "Student Registration System " << endl;

	  for(;;){
	  cout << "Enter a command: " << endl;
      cin >> command;

	 

	  if(command == PrintWrtSurname){
	  
		  // StudentList.printwrtSurname(); //
		  cout << "done printing w.r.t surname" << endl;}

	  else if(command == PrintWrtId){
	  
		  // StudentList.printwrtId(); //
		  cout << "done printing w.r.t id" << endl;}

		else if (command == Quit){

				cout << "done " << endl;
				return;}
			
			 else cout << "no such command as: " << command << endl;
	  }
}


int main(){

	// StudentList	cmpe160;

	// createStudentList("studentFile.txt", cmpe160);

	editStudentList(/* cmpe160 */);
      
      return 0;
}

this is the student list:
