<div style="font-family: 'Times New Roman'; font-size: 16px;">Hello, I am now in the book How to design a programm second edition at the point I have to design functions. Now I wonder if I understand this part right so I have made this function. ;String -> String ;This function takes out the first character of a given string with the name s ; given "roelof" expect "r" ; given "example" expect "e" (define (string_first s) ( if (eq? (string? s) true) (string-ith s 0 )"You have not entered a string")) So I hope somone can give me feedback on my first attempt so i can learn from it. Regards, Roelof </div>
