In main, declare an object of the student class then use it to call DisplayStudentDetails().

Thanks that was helpful advice

Code:

/*C++ program to create student class, Get and display student's details GGC  */
#include <iostream>
using namespace std;
 
 
void getDetails(void);
void DisplayStudentDetails(void);
 
class student
{
    private:
        char  name[30];
        int   rollNo;
        char  branch[30];
 
    public:
        //member function to get student's details
        void getDetails(void)
        {
             cout << "Enter name: " ;
             cin >> name;
             cout << "Enter roll number: ";
             cin >> rollNo;
             cout << "Enter Branch: " ;
             cin >> branch;
        }
         
        //member function to display student's details
        void DisplayStudentDetails(void)
        {        
             cout << "name: "  << name <<endl;      
             cout << "roll number: "  << rollNo <<endl;   
             cout << "Branch: " << branch  <<endl;      
        }
    protected:
   
};
  
int main(void)
{
   
    // Declare an object of class student 
    student student1; 
     
     student1.getDetails()  ;
  
     student1.DisplayStudentDetails();   
      
    return 0;
}

Enter name: abhi
Enter roll number: 12
Enter Branch: e
name: abhi
roll number: 12
Branch: e
