Table of Contents

Problem Statement

Some languages provide the facility to declare functions and subroutines through the use of function prototyping.

Demonstrate the methods available for declaring prototypes within the language. The provided solutions should include:

Languages that do not provide function prototyping facilities should be omitted from this task.

Let's start with the solution:

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

Source code in the nim programming language

# Procedure declarations. All are named
proc noargs(): int
proc twoargs(a, b: int): int
proc anyargs(x: varargs[int]): int
proc optargs(a, b: int = 10): int

# Usage
discard noargs()
discard twoargs(1,2)
discard anyargs(1,2,3,4,5,6,7,8)
discard optargs(5)

# Procedure definitions
proc noargs(): int = echo "noargs"
proc twoargs(a, b: int): int = echo "twoargs"
proc anyargs(x: varargs[int]): int = echo "anyargs"
proc optargs(a: int, b = 10): int = echo "optargs"
