Which version of c++ is it?

Can someone please tell me which version of c++ is this code written in?

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
long T, j, temp, N, s;
cin>>T;
for(j=0; j<T; j++)
{
cin>>N;
s=0;
for(temp=N/5; temp>0; temp/=5)
s+=temp;
cout<<"\t\t\t\t"<<s<<endl;
}

}

Which version of c++??? You just made it sound like a software version of a product called “c++”.
I assume you meant the c++ standard. Given code is simple c++. Any common c++ compiler should be able to compile it.

There may be some differences in different compilers of c++ . For ex. conio.h is supported by turboc++ but not many others .
In some compilers you need to write system(“cls”) instead of clrscr() for example .
