Setter and Getter Function

Program to set the first and second values of the two objects to display the values and add numbers.

#include<iostream>
#include<conio.h>
using namespace std;
class myFirstClass
{
private:
  int num1;
  int num2;
public:
  void setValue(int a,int b) //setter
  {
  num1=a;
  num2=b;
}
int getValue1()
{
  return num1;
}
int getValue2()
{  
  return num2;
}

int addFirstNum(myFirstClass obj)
{
  int num1Total;
  num1Total=num1+obj.num1;
  return num1Total;
}
int addSecondNum(myFirstClass obj)
{
  int num2Total;
  num2Total=num2+obj.num2;
  return num2Total;
}
};
int main()
{ 
  myFirstClass obj1;
  myFirstClass obj2;
  int a,b,c,d;
  cout<<"------------------Setterss---------------------------\n";
  cout<<"Enter the first value for the first object:\n\n";
  cin>>a;
  cout<<"Enter the second value for the first object:\n\n";
  cin>>b;
  cout<<"Enter the first value for the second object:\n\n";
  cin>>c;
  cout<<"Enter the second value for the second object:\n\n";
  cin>>d;

  obj1.setValue(a,b);
  obj2.setValue(c,d);
  cout<<"------------------Getterss---------------------------\n";
  cout<<"\n\nFirst value of first object obtained by getter:\n\n"<<obj1.getValue1();
  cout<<"\n\nSecond value of first object obtained by getter:\n\n"<<obj1.getValue2();
  cout<<"\n\nFirst value of second object obtained by getter:\n\n"<<obj2.getValue1();
  cout<<"\n\nSecond value of second object obtained by getter:\n\n"<<obj2.getValue2();
  //now for addition:
  cout<<"----------------Addition Result-----------------------\n";
  cout<<"Result after addition of first values of the two objects is:"<<obj1.addFirstNum(obj2);
  cout<<"\n\nResult after addition of second values of the two objects is:"<<obj1.addSecondNum(obj2);
  getch();
