Question

伙计我在下面给出的API用于表格显示，并且不想对最后一列进行排序。 https://cdn.datatables.net/r/bs-3.3.5/jqc-1.11.3,dt-1.10.8/datatables.min.js

Answer 1

您可以使用

#include <conio.h>
#include <stdio.h> 


typedef struct registered
{
    int compcode;
    char compname[20];
    int pinID;
    int custID;
    char IDtype[15];
    int compID;
}REGISTERED;

void AddUpdate(REGISTERED info);
void SellPetrol();

void main(){
    REGISTERED info = {0, "Apple", 0, 0, "passport", 0};
    REGISTERED list;
    AddUpdate(info);
    SellPetrol();

}

void AddUpdate(REGISTERED info){
    int choice;


    FILE *registryfile = NULL;
    registryfile = fopen("Sales.dat", "ab");


    if (registryfile == NULL){
        perror("Error: ");
    }
    else{
        do{


            printf("Company Code: ");
            scanf("%d", &info.compcode);
            printf("Company Name: ");
            scanf("%s", &info.compname);
            printf("Pin: ");
            scanf("%d", &info.pinID);
            printf("Customer ID: ");
            scanf("%d", &info.custID);
            printf("ID type: ");
            scanf("%s", &info.IDtype);
            printf("Company ID: ");
            scanf("%d", &info.compID);  

            fseek(registryfile, (info.compcode - 1) * sizeof(REGISTERED), SEEK_SET);
            fwrite(&info, sizeof(REGISTERED), 1, registryfile); 


            printf("Enter choice: ");
            scanf("%d", &choice);
        }while(choice == 1);
    }
        printf("\tCompany Code: %d\t\n", info.compcode);
        printf("\tCustomer ID: %d\t\n", info.custID);
    fclose(registryfile);
}

void SellPetrol(){

    int code = 0, PIN;

    REGISTERED list;
    FILE *registryfile = NULL;
    registryfile = fopen("Sales.dat", "rb");

    if (registryfile == NULL){
        perror("Error: ");
    }
    else{

        printf("Please enter the company code: ");
        scanf("%d", &code);
    //  printf("Please enter the PIN: ");
    //  scanf("%d", &PIN);

        rewind(registryfile);
            fseek(registryfile, (code - 1) * sizeof(REGISTERED), SEEK_SET);
            fread(&list, sizeof(REGISTERED), 1, registryfile); //reads data into list

            fflush(stdin);  
            printf("Company Code: %d\n", list.compcode);
            printf("Company Name: %s\n", list.compname);
            printf("Pin: %d\n", list.pinID);
            printf("Customer ID: %d\n", list.custID);
            printf("ID Type: %s\n", list.IDtype);
            printf("Company ID: %d\n", list.compID);

    }
    fclose(registryfile);
}

<select > <option value="volvo">Volvo</option> <option value="saab" (click)="get()">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> get() { alert('hi'); }指向最后一列。
