Solution to Tutorial 2: Simple input/output program
This program illustrations the following techniques:
- reading strings from the terminal
- labeling information
- combining two strings
- printing strings to the terminal
This program uses the command-line interface (CLI) library.
uses "http://www.dallycot.net/ns/cli/1.0#";
The first order of business is to prompt for the user’s name. The input-string function accepts a prompt and returns the string that was typed in.
name := input-string("What is your name? ");
Now that we have a name, we can concatenate the name with the greeting.
greeting := "Hello, " ::> name ::> ".";
Finally, we print the greeting.
print(greeting);
This ends the program.
