I need help with this code

Constructer is abnormally called again n again.... add these file 2 a project n run ...i've given given constant messages in da code to explain the problem!

Hit (1) two tyms i.e GetInput function in da menu.... u'll get 2 knw wat da problem is...

i've created an array of objects ....n when i jump 2 da next index da values of old index's r chenged to da default values ( da values assinged in constructer)!!!!

i've attached the files of prject...!

#include"AR.h"

#include<iostream>
using namespace std;
#include<conio.h>
#include<stdio.h>
AR::AR(
	  
	   
	   ){}
int AR::stdcount;

void AR::getInput(){
system("cls");
			
					cout<<"Enter Roll NO:"<<endl;
				 cin>>arr[stdcount].rollNo; 

				 
				 cout<< "The current index is holding the same value of roll no i.e arr["<<stdcount<<"].rollno is: "<<arr[stdcount].rollNo<<endl;
				 			
				 cout<<endl<<endl<<"But abnormally when this function is called again for the next index,the old value of arr[0].rollno (the previous index) is changed to the constructer value!!! constructer is bieng called abnormally. "<<endl<<endl;
				 
                 stdcount==1? cout<<"Now the roll no of 0th index is:"<<arr[0].rollNo<<",Which is the default value in costructer. It should be called only once when the instance was created! "<<endl : cout<<"Go for option(1)i.e GetInput once again in the menu "<<endl<<endl;	
				 
				 system("pause");
				 /*
				 cout<<endl<<"Enter Name:"<<endl;
				 cin>>arr[stdcount].name;

                 cout<<"Enter Quiz # 1 Marks "<< endl;
                 cin>>arr[stdcount].q1marks;
                 
                 cout<<"Enter Quiz # 2 Marks: "<< endl;
                 cin>>arr[stdcount].q2marks;
     
                 cout<<"Enter Assingment # 1 Marks: "<< endl;
                 cin>>arr[stdcount].a1marks;
     
                 cout<<"Enter Assingment # 2 Marks: "<< endl;
