Hello,
This is my first time here, i'm taking a programming class and no one was able to help me with my question.
I want to scan a string and then display each character of the string on a separate line.
i can't figure out the command to use, i think we should use a function recall.
i can't even figure out how to do the flowchart on it. any ideas?

Oh! That's tooo easy.
Do it two ways: iteratively, and recursively. :p
include <string.h> for string handling
if string = "Abbracadabbra", then
get it's strlen(string), and say it's length
then
for(i=0;i<length;i++)
....print the string[i] and a \n (newline char).
using the right %c format for printf(), of course.
for input: scanf("%s", string) is normal. Scanf() has all kinds of format specifiers you can use to tweak the string for length, stop storing the char's with a certain letter, etc. Watch scanf() though, it will quit on you unexpectedly. Hates spaces! It's return value (an int), can be used to help moderate it's quirkyness.
fgets() is the better choice for user input, generally.
I'm leaving you with work to do, quite on purpose.
Adak! thanks for the fast reply! this is really great! i'm glad i signed up!
okay so i followed your steps, and i got stuck with the correct %c format
the lesson i'm working on is function, so somewhere i should include a function,
how is it possible to make a function with string/character?
here's what i have:
#include <stdio.h>
#include <string.h>
int main ()
{
int i;
int length;
char string[50];
printf ("Enter a sentence: ");
gets (string);
printf ("The sentence entered is %u characters long.\n",strlen(string));
strlen(string) == length;
for(i=0;i<length;i++)
printf("%c\n", string); /* i'm having a problem here i don't know which %c format to use*/
getch();
}
Thank you
Code:#include <stdio.h>
#include <string.h>
int main (void) <---- correct format for main()
{
int i;
int length;
char string[50];
printf ("Enter a sentence: ");
gets (string); <---- scanf("%49s", string); is safer... no buffer overflows
printf ("The sentence entered is %u characters long.\n",strlen(string));
strlen(string) == length; <---- you are assigning this incorrectly.
for(i=0;i<length;i++)
printf("%c\n", string[i]); <--- you need the array index
getch();
}
Okay sweet! i got it!
Thank you guys!
does anyone know by any chance what is the correct command to use for Raptor (flowchart) ?
If your 'string' contains space, you want to use fgets().Quote:

No, not familiar with it.Quote:
