1. Introduction

Determining the largest among a set of numbers is a fundamental programming problem that helps beginners understand conditional structures. In this guide, we'll create a Go program to identify the largest number among the three provided inputs.

2. Program Overview

Our Go program is architected to:

1. Request the user to input three distinct numbers.

2. Evaluate and identify the largest among the three numbers.

3. Present the determined largest number to the user.

3. Code Program

// Initiation of our Go program is marked by the main package declaration. package main // We integrate the fmt package for managing input and output operations. import "fmt" // Function to ascertain the largest among three integers. func findLargest(x, y, z int) int { if x > y { if x > z { return x } else { return z } } else { if y > z { return y } else { return z } } } // The main function is the entryway to our program's execution. func main() { var a, b, c int // We solicit the user to provide three numbers. fmt.Print("Enter three numbers separated by spaces: ") fmt.Scan(&a, &b, &c) // The largest among the three numbers is determined and then displayed. fmt.Printf("The largest number among %d, %d, and %d is: %d\n", a, b, c, findLargest(a, b, c)) } 

Output:

For instance, if the user provides the numbers 12, 29, 7, the output of the program would be: The largest number among 12, 29, and 7 is: 29 

4. Step By Step Explanation

1. Package and Import Directives: We initiate with package main indicating our program's start. The fmt package is adopted for I/O functionalities.

2. Function to Determine the Largest Number: The findLargest function takes in three integers. Through nested conditional statements, it discerns the largest among them.

3. Variable Initialization: Three integer variables (a, b, c) are declared to capture the user's input.

4. Gathering User Input: Using fmt.Print, a prompt is rendered, and the user's input is gathered using fmt.Scan.

5. Computing and Showcasing the Result: The findLargest function is summoned with the user's inputs, and the outcome is presented using fmt.Printf.
