Re: User input readline || readf

[Dennis Ritchie via Digitalmars-d-learn]

It also works:

-----
import std.conv;
import std.stdio;
import std.string;

struct Human {
        string name;
        ushort age;
}

void print_human_list(Human[] human_list) {

        foreach(human; human_list) {
                writeln(human.name);
                writeln(human.age);
        }
        writeln();
}

void add_new_human(ref Human[] human_list) {

        write("Name: ");
        string name = readln.strip;

        write("Age: ");
        ushort age = readln.strip.to!ushort;

        Human tmp_human = {name, age};
        human_list ~= tmp_human;
}

void main() {

        Human[] human_list;
        
        for(;;) {

                writeln("A)dd New Human.");
                writeln("P)rint Human List.");
                writeln("Q)uit.");
                write(": ");

                char choice = readln.strip.to!char;

                switch (choice) {
                case('A'):
                        add_new_human(human_list);
                        break;
                case('P'):
                        print_human_list(human_list);
                        break;
                case('Q'):
                        return;
                default:
                        continue;
                }
        }
}
