Linking C++ with Cplex: Error C1083:

Hi, i have installed Visual Studio 2017 and Cplex 12.8.0 and do the link between them. then i tried to write a simple code to verify the link btw.
using namespace std;
#include <ilcplex/ilocplex.h>

int main ()
cout << “Hello World!\n”;
return 0;

But i have an error: Cannot open include file: “iostream.h”, no such file or directory.
What should i do please? I have tried many solutions that i have dound in net but none have solved the problem.
Thanks in advance

is this a question related to legato ?
