C strcmp在相等的字符串上返回1

Question

我正在制作一个程序，首先会注册用户，然后将他引导到登录屏幕。在注册模块中，名称和密码（仅限数字）从用户输入，然后存储在文件中。然后在登录模块中，提示用户输入其用户名（名称）和密码。输入的名称和密码然后存储在变量中，然后与文件中的数据进行比较，如果相等则登录将成功。但是，即使数据完全相同，我从strcmp得到1。这是代码

我存储数据的结构

struct user_data                            
{
    char name[50];                              // Name of the user
    unsigned long password;    
};

注册代码：

void sign_up( void)
{
    scanf("%*c");

    FILE* data = fopen("data.txt","w");

    if ( data == NULL  ){
        printf("Unable to open file.");
        scanf("%*c");
        system("clear");
    }

    system("clear");
    printf("\t\t----------------------------\n"
           "\t\t|                          |\n"
           "\t\t|     SIGN UP PAGE         |\n"
           "\t\t|                          |\n"
           "\t\t----------------------------");

    printf("\n\nName:");
    fgets(new_user.name,sizeof(new_user.name),stdin);            
    printf("\n\n%s",new_user.name);

    printf("\nPassword.");
    scanf("%lu",&new_user.password);    // Getting pass into the struct
    printf("\n\n%lu",new_user.password);

    fprintf(data,"%s %lu\n",new_user.name,new_user.password);

    system("clear");
    printf("\n\nSign up complete. :)  ");
    printf("\nYou will now be redirected to the login screen.\n\n");

    fclose(data);
 }

登录代码

void sign_in(void)
{
    scanf("%*c");
    printf("\t\t----------------------------\n"
           "\t\t|                          |\n"
           "\t\t|     SIGN IN PAGE         |\n"
           "\t\t|                          |\n"
           "\t\t----------------------------\n");

    printf("\n\nName: ");
    fgets(data_ver.name,sizeof(data_ver.name),stdin);

    printf("\nPassword: ");
    scanf("%lu",&data_ver.password);

    FILE* data = fopen("data.txt","r");
    char name_ver[50];
    unsigned long pass_ver;

    fscanf(data,"%s %lu",name_ver,&pass_ver);
    int cmp = strcmp(data_ver.name,name_ver);
    printf("\n\n%d",cmp);

    printf("\n%s\t%s\n",name_ver,data_ver.name);
    printf("%lu\t%lu",pass_ver,data_ver.password);
    scanf("%*c");

    if ( (cmp == 0) && (pass_ver == data_ver.password)  )
    {
         system("clear");
         printf("\n\nLog in successfull. Welcome. :)");
    }
    else
         printf("\n\nLog in failed. Try again.");

    fclose(data);
}

演示输出

正如你在pic中看到的那样，我的数据准确无误但仍然是strcmp返回1
