I've just started and i try to compile sth but there is a small error

I apologise for this question probably it is a stupid question. when i try to compile the source code it says :
:7:16 error: expected identifier before "(" token

Code:

---

#include <stdio.h>
#include <stdlib.h>


int main()
{
 int x;
if (x >= 0) && (x < 14)
{
  printf("you are a kid");
}
else if (x => 14) && (x <= 35)
{
  printf("you are young");
}
else if !(x > 0) && (x <= 35)
{
  pritnf(" you are old");
}
system("pause");
return 0;
}

You need more ( )

It's

Code:

---

if ( your_logical_expression_goes_here ) {
}

---

Also there is no => operator
