Thread: Caracter input

Hey guys, I was wondering if there was a way to scanf/getchar() a string of characters into a table ?
Am i shooting for the stars or is it a possibility ?
what I'm trying to do is basically have the user input 4 characters, that's pretty much all i need but when the user hits enter, the characters would be assigned to elements of a table...

it should be doable i guess...

it's part of a mastermind game I'm creating. the game is pretty much OK except for that question i ask.
In the program, the user has 6 attempts at cracking a 4 color randomly picked code. normal way of running would be, user inputs 4 characters for red green blue and yellow (r, v, b, j - ie: rrbj - repetitions allowed)
when user hits enter, program prints out the numbers of hit&miss colors... if any of course and will keep prompting to enter a new code till either the 6 retries are over or if the user guessed the code..

My code is pretty much fine except for when a user enters a code... he either has to do each character at a time or enter the same code 4 times... which is not satisfactory.
The program needs to read the 4 character string and put it in a table with a simple for loop.

Here's my code

Code:

#include <stdlib.h>
#include <stdio.h>

#define NBCOLORS 4
#define NBTRIES 6

char readkey();
void createCode(char code[]);
int playGame(char code[]);

int main (void)
{
    char secretCode[NBCOLORS];
    createCode(secretCode);
    while(playGame(secretCode));
    return 0;
}


// Character input/storage

char readkey() {
    fflush(stdin);
    char c = '\n';
    while (c == '\n' || c == ' ')
        c = getchar();
    return c;
}

void createCode(char code[])
{
    int i;
    srand(1810);

    /* create random code */
    for (i = 0; i < NBCOLORS; i++)
       switch(rand() &#37; 4)
       {
           case 0: code[i] = 'r'; break;
           case 1: code[i] = 'b'; break;
           case 2: code[i] = 'v'; break;
           case 3: code[i] = 'j'; break;
       }  
}

int playGame(char code[]) {
    char codeCopy[NBCOLORS];
    int victory = 0;
    int i, j, k;
    char c = 0;                         /* character being read */
    
        
    for (i = 0; i < NBTRIES; i++) {
        int identical = 0;
        int present = 0;
        
        for (j = 0; j < NBCOLORS; j++)
            codeCopy[j] = code[j];
        
        printf("Votre coup (essai no %i): ", i+1);
        
        for (j = 0; j < NBCOLORS; j++) {
            c = readkey();
            if (codeCopy[j] == c) {
                codeCopy[j] = '#';
                identical++;
            }
            else {
                for(k = 0; k < NBCOLORS; k++)
                    if (codeCopy[k] == c) {
                        codeCopy[k] = '#';
                        present++;
                    }
            }
        }
        
        printf("Couleurs identiques: %i\n", identical);
        printf("Coleurs presentes: %i\n", present);
        
        if(identical == NBCOLORS) {
            printf("Bravo! Vous avez trouve notre sequence de couleurs\n");
            victory=1;
            break;
        }
    }
    
    if(!victory) {
        printf("Desole, la sequence de couleurs a deviner etait ");
        for (j = 0; j < NBCOLORS; j++)
            putchar(code[j]);
        putchar('\n');
    }
    
    while (c != 'o' && c != 'O' && c != 'n' && c != 'N') {
        fflush(stdin);
        printf("Voulez-vous jouer une autre partie? (O/N)?");
        c = readkey();
    }
    
    if (c == 'o' || c == 'O')
        return 1;
    return 0;
}

Thanks for any insight... this is puzzling me quite much

so getchar() only picks up a character at a time, is there any other way i can pick up a whole string, then for loop it to place each character of the string in a table?

And (un)fortunately the Windows runtime "supports" fflush(stdin), it seems; your code would probably work -- well, do what you want -- on my Mac machine, which doesn't flush stdin, and probably on a *nix machine as well. This is why we advise people to stay away from "extensions" where possible.

well it does work... not to my liking or the given directions but still, if the characters are put in one at a time followed by enter, everything is fine (or seems to be, at least)
I would do what I wanted if I knew what that was, or what my options were... hence why I'm asking my questions...
And excuse my ignorance on the topic but which extension are you talking about and all of this falls in the realm of the class outline... I'm only using what we've been taught.

I appreciate your input

edit:
the output should look like this: (considering the secret code to be rjbb)
Devinez la sequence de 4 couleurs chiosies (r: rouge, b: bleu, v: vert, j: jaune).
Vous avez 6 essais pour devinez cette sequence.

Votre coup (essai no 1): vvjr
Couleurs identiques: 0
Couleurs presentes: 2

etc etc

i get you, i need to call createCode at the point the program "restarts"
in the playGame function... just having some issues coding it... i'm getting some syntax error befor char...

Code:

int playGame(char code[]) {
    char codeCopy[NBCOLORS];
    int victory = 0;
    int i, j, k;
    char c = 0;                         /* character being read */
    createCode(char code[]);  >>> added call to createCode results in syntax error before char

edit:
I've replaced the bolded the following lines
char secretCode[NBCOLORS];
createCode(secretCode);

it still keeps the secretCode of the last "game"
am i missing something
/me scratches his head
