hello guys ! i have created a program just to understand how to return a value from using a recursive program
what it does it thati have have two variable i.e first and last
the value of first is zero and last is 10
not i want the function to continue until last ==to first
if not it would simply return the value of the last and decrement here is the code and the prob listed and yes i am noob
#include<conio.h>
#include "stdafx.h"
#include <iostream>
# define size 10;
int mergesort(int,int);
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
int first=0,last=10;
//cout <<" enter the vlaues";
//for(int i=0;i<10;i++)
//cin>>arr[i];
cout<<mergesort(first,last);
system("pause");
system("pause");
return 0;
}
int mergesort(int first,int last,int mid)
{ int a=34343434;
cout<<"mergesort called";
if(first==last)
{
cout<<"its the end of the world";
return a;
}
if(first=!last)
{last--;
cout<<"\n"<<last;
mergesort(first,last,mid);
return last;
}
return first;
}
here is the prob and plz tell me how to over come it
