go read user input

To read user input in the Go programming language and provide explanations for each step, you can follow the steps below:

1. Import the necessary packages: In Go, you need to import the "fmt" package to use the standard input/output functions. You can do this by adding the following line at the beginning of your program:

import "fmt"

1. Prompt the user for input: Use the Println function from the "fmt" package to display a prompt message asking the user to enter some input. For example, you can use the following line of code:

fmt.Println("Please enter your input:")

1. Read user input: To read the user's input, use the Scanln function from the "fmt" package. This function takes a pointer to the variable where the input should be stored. For example, if you want to read the input into a variable called input, you can use the following line of code:

fmt.Scanln(&input)

1. Process the user input: Now that you have the user's input stored in a variable, you can perform any necessary processing or calculations based on that input.

2. Display the results: Use the Printf function from the "fmt" package to display the results of your processing or calculations. For example, if you want to display the user's input, you can use the following line of code:

fmt.Printf("You entered: %s\n", input)

Note: Remember to replace %s with the appropriate format specifier based on your variable type.

That's it! By following these steps, you can read user input in Go, process it, and display the results.
