如何将从文件中获取的2-3位数字放入数组？

Question

main ()
{
        FILE *pRead;
        FILE *pWrite;
        char lastname [20];
        char firstname [20];
        char grade [4];
        char gradefi [4];
        char gradeltr [3];
        int i=0;

        pRead=fopen ("testtext.dat", "r");

        if (pRead == NULL || pWrite == NULL)
                printf ("\nFile cannot be opened\n");
        else
                printf ("\nContents of testtext.dat\n\n");
                fscanf (pRead, "%[^,]%[^\n]%s", lastname, firstname, &grade);
                printf ("\n");
                pWrite=fopen ("report.txt", "w");
                fprintf (pWrite, "%s %s %s\n", firstname, lastname, &grade);
        while (!feof(pRead))
                {
                        ++i;
                        printf ("%s %s %s\n", firstname, lastname, &grade);
                        fscanf(pRead, "%[^,]%[^\n]%s", lastname, firstname, &grade);
                        fprintf (pWrite, "%s %s %s\n", firstname, lastname, &grade);
                }

fclose(pRead);
fclose(pWrite);

printf ("\nThere are %d student(s) in this list\n", i);

好吧，我不想看起来像一个陈旧的偏执放屁或任何东西，但我建议您在else后面的后续语句周围放一些大括号，看看会发生什么。
