What I have tried:

i have tried by placing switch case inside the main() class but it shows many errors and warnings and the code has not even run once.

Looks like something went wrong while posting the code. Use 'Improve question' and post your code again.
thesnehad 23-Jul-22 8:27am    
thanks for help
thesnehad 23-Jul-22 8:30am    
is the code understandable now?
0x01AA 23-Jul-22 8:35am    
Yes, now the code is readable.
thesnehad 23-Jul-22 8:42am    
any ideas how to solve?

If this is to become a standards-compliant C++ program, the correct headers should be used:
Neither <iostream.h> nor <conio.h> exist under C++.
//#include <iostream.h>	  
#include <iostream>
// #include <conio.h>
using std::cout;

The getdata() member function cannot work like this.
C++
void getdata()
{
  cout << "Select menu";
}
do {
...
} while (select_menu != 5);

On the one hand, curly brackets are wrong, on the other hand, the select_menu variable is not read in, so the do-while loop does not work. It would be better to separate the declaration of the class from the implementation. Preferably in two separate files.
C++
// menu.h
class menu
{
public:
	int getMenu();
	// ...
private:
	char select_menu;
	char name[20];
	char branch[20];
	int en_no;
};

C++
// menu.cpp
int menu::getMenu()
{
   cout << "Select menu\n";
   // ...
   return select_menu;
}


//Edit:
Since several similar data records are to be managed later on, it makes sense to manage them in a separate structure or class.
C++
typedef struct {
	std::string name;
	std::string branch;
	int en_no;
} studentdata;

Containers such as string, array, vector, ... are preferably used under C++.

Have my 5.
I don't agree with you that separating declaration and implementation will help. That's why I love c#. But that is only personal preference :-)
merano99 23-Jul-22 10:05am    
thanks ;-)
thesnehad 23-Jul-22 11:34am    
Thanks for the help!!
But my task is to do this program under iostream header file
merano99 23-Jul-22 14:30pm    
My condolences that you have to use an outdated compiler. It may be that my suggestions will also work with your C++-like compiler, but some things may also not work.
thesnehad 24-Jul-22 5:45am    
okay!!
I should not doing it but I do it. I post here your code which is compilable (see below, several TODO comments). But even the code compiles it does not mean it works. It is very questionable whether it will help.

I strongly assume you did not write that code by yourself. This because if one write code one do it step by step and when you are doing it step by step you seldom end in a mess like this ;)

I suggest you do start from scratch and first think about what are the requirements and how you would solve that step by step.

Here the compialable code. Most probably not really helpfull, but maybe it helps you to sove some basic mistakes ;)

Thanks a lot for your help.
Actually I took ideas from the sample code and tried to write it by my self but unfortunately it's going the way opposite it had thought.
And after all the errors which I saw my mind didn't work
Thanks for that I will try hard to work on that.
0x01AA 23-Jul-22 12:36pm    
And I think you should start with some more easy examples to get familiar with c++.

All the best and stay tuned ;)
