You did say "generally".  But since we're talking about Ruby in this
thread and since you're responding to someone who was specifically
comparing Ruby and C, I think it's worth pointing out that Ruby, and
perhaps object-oriented scripting languages in general, are almost
always shorter than C, even for those "simple things".

Since you gave "getchar/scanf vs. messing with an array" as an
example...

C: ====

#include <stdio.h>

int main()
{
    printf("How old are you? ");
    int age;
    scanf("%d", &age);
    printf("Next year you will be %d.\n", age + 1);
}

Java: ====

import java.io.*;

public class AgeQuestion
{
    public static void main(String[] arguments) throws IOException
    {
        System.out.print("How old are you? ");
        BufferedReader input =
             new BufferedReader(new InputStreamReader(System.in));
        String age_string;
        age_string = input.readLine();
        int age = Integer.parseInt(age_string);
        System.out.println("Next year you will be " + (age + 1) +
".");
    }
}

Ruby: ====

print "How old are you? "
age = gets.to_i
puts "Next year you will be #{age + 1}."

So yes, Java is more verbose than C.  But C is more verbose than Ruby.
