Question
B) Answer the following in one or two sentences : [5 × 1 = 5]a) List different data types in GO programming.b) What is blank identifier?c) Justify True or False : Functions can be passed as an argument toanother function in GO.d) What is empty interface?e) What is package?
Solution
a) Different data types in GO programming include integers, floating-point numbers, complex numbers, boolean, strings, and derived types such as arrays, structures, unions, and pointers.
b) A blank identifier in Go is represented by the underscore (_) and is used when syntax requires a variable name but program logic does not. It is a way to ignore values that a function returns.
c) True. In Go, functions are first class citizens, meaning they can be passed as arguments to other functions, just like other types such as int, float64, etc.
d) An empty interface in Go is an interface that has zero methods. It is represented as interface{}. Since it has zero methods, all types implement the empty interface.
e) A package in Go is a way to group related Go source files together. It's a unit of source code distribution and provides code encapsulation and reusability.
