Can't find errors

[ruby09]

1)what is wrong with the following program?
#include<iostream.h> //Line 1
using namespace std; //Line 2
int main() //Line 3
{
intx = 0; //Line 4
cout<<"x="<<x<<endl;
return 0;
}

2)what is wrong with the following program>
#include<iostream> //Line1
#include<cmath> //Line2
using std; //Line3
int main() //Line4
{
return 0; //Line5
}

try to use the #format when uploading code

1) intx = 0; should be int x = 0; and maybe you must include iostream instead of iostream.h

2)using namespace std; instead of using std;

Your compiler gives error messages, right? It isnt really hard to find those errors...
