    Printing individual characters from fgets using an array

    Hi, I'm trying to write a program that takes a text file as an output, and prints the text of that file to a column size defined by the user.

    Here's my printing loop so far, when I run it, it just crashes the program. What should I change?

    Code:
    while ((fgets(fileChars, MaxLineSize, fp)) != NULL) // MaxLineSize is a #define to 100
                {
                    stringLen = strlen(fileChars);
                    printf("%d", stringLen);
                    if (stringLen > columnWidth)
                    {
                        for (j = 0; j < columnWidth; j++)
                        {
                            printf("%s", fileChars[j]);
                        }
                        printf("\n");
                        for (j = columnWidth; j < stringLen; j++)
                        {
                            printf("%s", fileChars[j]);
                        }
                    }
                    else
                    {
                        printf("%s",fileChars);
                    }
                    
                }

    Use %c to print an individual char.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
