the.mesha.stele.is.the.earliest.known.writing.with.any.punctuation
Computer programmers love punctuation marks. The C and Java
programming
languages have special meaning for almost every special character
on the keyboard. The only excepts are `
, @
,
$
and _
, though _
is often
treated as a letter.
#include <stdio.h> #include <stdlib.h> /* * A program example from CSCI 255 */ int main(int argc, char** argv) { int count, num ; puts("Enter a number") ; scanf("%d", &num) ; count = 0 ; while (num != 1) { printf("%8d\n", num) ; if (num%2==0) { num = num/2 ; } else { num = 3*num + 1 ; } ++count ; } printf("%8d\n\n", num) ; printf("iterations: %d\n", count) ; return (EXIT_SUCCESS); }
