Explanation

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

Here, we created the main() function. The main() function is the entry point for the program. In the main() function, we created the variable num, which is initialized with 0. Then we read the value from the user. After that, we checked the given number is greater than or equal to 0 then the number will be POSITIVE otherwise the number will be NEGATIVE.
