Thread: Segmentation fault

Hey!
I keep getting a segmentation fault and I have no clue how to fix it.
Does anyone know what I'm doing wrong?

Code:

#include "libpynq.h"
#include <stdio.h>
#include <string.h>
#define MAXWORDS 10
#define MAXLENGTH 30


int numberOfWordsInDict(char dict[MAXWORDS][MAXLENGTH])
{
    int numbers=0;
    for(int i=0; i<MAXWORDS; i++){
        for(int j=0; j<MAXLENGTH; j++){
            scanf("%c", letter);
            while(dict[j][i] != '\0'){
                numbers++;
            }
        }
    }
    printf("The dictionary contains %d words.\n", numbers);
}


int main (void)
{
    char array[MAXWORDS][MAXLENGTH] = {{""}};
    char input;
    printf("Command [qnaprslo]? ");
    scanf(" %c", &input);


    while(input != 'q')
    {
        if(input == 'n')
        {
            numberOfWordsInDict(array[MAXWORDS][MAXLENGTH]);
            printf("Command [qnaprslo]? ");
            scanf(" %c", &input);
        }
        printf("Unknown command '%c'\n", input);
        printf("Command [qnaprslo]? ");
        scanf(" %c", &input);
    }
    if(input == 'q')
    {
        printf("Bye!\n");
        return 0;
    }
}
