Thank you very much for this suggestion. I have been wanting to try functional programming for a long time, after seeing so many inscrutable and concise solutions on Project Euler. I never managed to get far with Haskell, though. In addition to the web version you linked to, Chris Krycho has created a nicely-formatted Kindle version. I am 4% through it and managed to write my first Scheme code for Exercise 1.3: "Define a procedure that takes three numbers as arguments and returns the sum of the squares of the two larger numbers." delta, how's your progress coming?
I am using a handy online interpreter. (define (square a) ( * a a))
(define (sumofsquares a b) (+ (square a) (square b)))
(define (<= a b) (or (< a b) (= a b)) )
(define (sosbig2 a b c)
(cond
( (and (<= a b) (<= a c)) (sumofsquares b c))
( (and (<= b a) (<= b c)) (sumofsquares a c))
( (and (<= c a) (<= c b)) (sumofsquares a b))))
Well, I decided I didn't like Scheme's syntax + there aren't many frameworks & libraries that support it. I'm learning C now, and I like it a lot more. The main reason I'm learning C is that I plan to use OpenWRT for a science fair. Your code above is pretty damn beautiful, though. I wrote a program yesterday because my sister wanted a program related to flowers. (✿◠‿◠)
#include <stdio.h>
main()
{
int rose_amt = 12;
int daisy_amt = 7;
int tulip_amt = 23;
int sunflower_amt = 42;
int rose;
int daisy;
int tulip;
int sunflower;
int exit_value; printf("This program will calculate the grand total number of days\nit will take for four different kinds of flowers to grow.\n\n");
printf("Roses take %d days to grow.\n", rose_amt);
printf("Daisies take %d days to grow.\n", daisy_amt);
printf("Tulips take %d days to grow.\n", tulip_amt);
printf("Sunflowers take %d days to grow.\n", sunflower_amt); printf("\nHow many roses do you wish to plant?\n");
scanf(" %d", &rose ); printf("How many daisies do you wish to plant?\n");
scanf(" %d", &daisy); printf("How many tulips do you wish to plant?\n");
scanf(" %d", &tulip); printf("How many sunflowers do you wish to plant?\n");
scanf(" %d", &sunflower); printf("\nIt will take a grand total of %d days for all the flowers to grow.\n", rose*rose_amt+daisy*daisy_amt+tulip*tulip_amt+sunflower*sunflower_amt);
printf("\nWould you like to exit?\n");
scanf("%d");
return 0;
}
