到底是哪里导致死循环了呢?


void show() {
    FILE* fp;
    int ch;
    int stupos = 0;
    fp = fopen("C:\\Users\\ALIENWARE\\Desktop\\student.txt", "r");//以r模式打开文件
    if (!fp) 
        return;
    while (EOF != (ch = fgetc(fp))) {
            if (ch == 10) {
                stupos++;
            }
            putchar(ch);
        }
        TotalCount = stupos;
        printf_s("一共有%d名学生", TotalCount);
        fclose(fp);
}

测试没问题。可能在别的代码里?
