No, you can't declare an integer data type. Int means Integer Data type.

There an option you can define an integer as an int. You just wanted use integer in place of an int so you can define it.
Just use #define integer int
This will let you declare a variable with integer keyword.

You can do it in some cases.
In Java, Integer x = 0; would work because it will be automatically converted to Integer type. In fact, it's more efficient than Integer x = new Integer(0);
In C++, you can make integer class and overload operators to convert to int and make single parameter constructor, then your code will be correct.
