Step by Step solution about How to resolve the algorithm Function prototype step by step in the Go programming language

Function Declarations:

In Go, function declarations define a function's name, parameters, and return types. The syntax is as follows:

func functionName(parameters) returnType { ... }

a() Function:

• This function has no arguments, as indicated by the empty parentheses ().
• It is a valid function declaration without any parameters.

b(x, y int) Function:

• This function takes two arguments: x and y, both of type int.
• The int type in Go represents integers.

c(...int) Function:

• This function uses a variadic parameter. A variadic parameter is a special type of parameter that can take a variable number of arguments.
• The ... before the parameter type indicates that it is a variadic parameter.
• In this case, the parameter is a slice of int values, meaning the function can take an arbitrary number of integers as input.

func a()          // function with no arguments
func b(x, y int)  // function with two arguments
func c(...int)    // varargs are called "variadic parameters" in Go.
