Why Does it Write Only Once to File And Never Again

[akerr95]

I am working on a project( almost finished) but this last part is ridiculously killing me Here is the code I have:

Ca_Info rpd[data];
    int i=0, choice, transnum,regch,ret=0;
    trans ruc;
    Ca_Info rting;
    FILE *rfp,*verfp;
    char stat[]="available";
 
    rfp=File_Handler(rent,App_Read);
    verfp=File_Handler(veh,Read_B);
    FindByStat(stat,rpd);
    printf("\t\t\tAvialable List\n");
        while(1)
        {
            if ((strcmp(rpd[i].status,stat)!=0) &&(i==0))
            {
                printf("No Cars to rent\n");
                system("pause");
                return;
            }
            if(strcmp(rpd[i].status,stat)!=0)
            {
                break;
            }
            printf("-----------------------\t-----------------------\t-----------------------\t\n");
            printf("-----------------------\t|         %d          |\t-----------------------\t\n",i+1);
            printf("-----------------------\t-----------------------\t-----------------------\t\n");
            printf("Reg.No:%d   Year:%d   2:No.of Seats:%d  3:Type:%s    4:Model:%s\n5:Colour:%s   6:Status:%s   7:Rent Rate:%.2f   8:Insurance Rate:%.2f\n",rpd[i].regnum,rpd[i].year,rpd[i].no_Seats,rpd[i].type,rpd[i].model,rpd[i].col,rpd[i].status,rpd[i].rent_Rte,rpd[i].irancRte);
            printf("-----------------------\t-----------------------\t-----------------------\t\n");
            i++;
        }
    printf("Enter Number choice for car\n");
    scanf("%d",&choice);
    memcpy(&rting,&rpd[choice-1],sizeof(rpd[choice-1]));
    system("cls");
    printf("Enter date\n");
    scanf("%d %s %d %s %d",&ruc.dte.DD,&ruc.dte.sls,&ruc.dte.MM,&ruc.dte.sls1,&ruc.dte.YY);
    printf("Enter customer full name(Use - for spaces)\n");
    scanf("%s",ruc.c_Nme);
    printf("Enter driver's License #\n");
    scanf("%d",&ruc.d_Lic);
    printf("Enter address(Use - for spaces)\n");
    scanf("%s",ruc.addr);
    printf("Enter name of a sponsor(Use - for spaces)\n");
    scanf("%s",ruc.spon_Nme);
    printf("Enter duration of rental in days\n");
    scanf("%d",&ruc.time);
    printf("Enter credit card number\n");
    scanf("%s",ruc.cre_Crd);
    printf("Enter name on credit card(Use - for spaces)\n");
    scanf("%s",ruc.crd_Own);
    ruc.ins_Cost= rting.irancRte * ruc.time;
    ruc.rnt_Cost= (rting.rent_Rte * ruc.time)+ruc.ins_Cost;
 
            while(1)
            {
                Random(ruc.transnum,6);
                ret = FindInfo(rfp,NULL,atoi(ruc.transnum),0);
                    if (!ret)
                    {
                        continue;
                    }
                    else
                    {
                        break;
                    }
            }
            strcpy(rting.status,"Out");
            fflush(rfp);
            fprintf(rfp,"%s\t%d\t%d\t%s\t%d%s%d%s%d\t%d\t%.2f\t%.2f\t%s\t%s\n",ruc.transnum,rting.regnum,ruc.d_Lic,ruc.c_Nme,ruc.dte.DD,ruc.dte.sls,ruc.dte.MM,ruc.dte.sls1,ruc.dte.YY,ruc.time,ruc.ins_Cost,ruc.rnt_Cost,ruc.cre_Crd,rting.status);
            regch=rting.regnum;
            Update(regch);
            fclose(rfp);
            fclose(verfp);
}

I have no idea.

There is only one fprintf at the end of your posted code so you would write once.

However, I can't tell what's happening from the code snippet that was posted. The code is part of some function and it would help to see the entire function.

Line 8 uses File_Handler to presumably open file rfp.
Line 57 uses FindInfo to do something with file rfp.
Line 68 flushes file rfp.
Line 69 prints one line to file rfp.
Line 72 closes file rfp.

Are you opening file rfp for read, write, or append? Do you select update mode? Refer to description of the fopen mode argument.
