C，从文件读取到数组，按数字进行编号

void readfromFile() {

    FILE *myFile;
    myFile = fopen("matrikel.txt", "r");

    //read file into array
    int numberArray[12];
    int i;

    if (myFile == NULL) {
        printf("Error Reading File\n");
        exit (0);
    }

    for (i = 0; i < 12; i++) {
        fscanf(myFile, "%d,", &numberArray[i] );
    }

    for (i = 0; i < 1; i++) {
        printf("Number is: %d\n\n", numberArray[i]);
    }

    fclose(myFile);
}
void readfromFile() {

    FILE *myFile;
