Thread: Splitting a String into Separate Characters, or an Array

I have been looking everywhere, but the only place I have seen it done is Objective C. The Question: how do I split a string, input by the user, into an array of characters? No code shown because I know no commands that do this.


--Input by user as in fgets, or scanf().

A C string, by definition, is an array of characters terminated with a null character ('\0'). So to read and save a string, you need a character array to store it in*. Therefore, in response to your question, the work has already been done.

Code:

#include <stdio.h>

#define MAX_LEN 64

int main(void)
{
    char input_string[MAX_LEN];  /* character array to store the string */
    int i;

    printf("Enter a string:\n");
    fgets(input_string,sizeof(input_string),stdin);  /* read the string */

    /* print the string as a whole */
    printf("\nYour string printed out as a string:\n");
    puts(input_string);

    /* print the string by printing each element of the array */
    printf("Your string printed out as individual characters:\n");
    for(i=0; input_string[i] != '\0'; i++)
    {
        putchar(input_string[i]);
    }

    return 0;
}

This is the answer to the question you asked. If you actually meant something different, please clarify the question.

* Well, there are other ways, such as saving the string in dynamically allocated memory through a pointer, but using a character array would seem to suit your purposes.
