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 four variables num1, num2, num3, large, which are initialized with 0. Then we read the values of variables from the user. After that, we checked all numbers and find the largest number among the three numbers and print the largest number on the console screen.
