How to make a file, i try to make a file.txt in c but i got an error, the program where i write successed execute but in file or in notepad the contents do not exist.

Code:

this my snippet of my code what I want to input to file.txt:
    int a,b,c,d,e = 0,f = 0;
    int check,check2,check3;
    int *fptr;
    fptr = fopen("file.txt","w");
    
    printf("\nenter the amount of food to be purchased  : ");
    check=scanf("%d", &b);
    printf("\n");
                
    if (check != 0) {
     for (a=1; a<=b; a++){
       printf("the price of food of- %d \t : ",a);
       check2=scanf("%d", &c);
       printf("\n");
                    
       if (check2==0) {
         printf("Please enter in numeric !!\n");
         while ((getchar()) != '\n'); 
         system("PAUSE");
         goto cashier;
       }
       printf("the amount ordered \t : ");
       check3=scanf("%d", &d);
       printf("\n");
                    
       if (check3==0) {
         printf("Please enter in numeric !!\n");
         while ((getchar()) != '\n'); 
         system("PAUSE");
         goto cashier;
       }
        e=c*d;
        f+=e;
    }
    printf("total price of food  \t : Rp.%d",f);
    printf("\n");
    
    char isTrue;
    printf("\n\nPush [Y] to save a copy from your payment [T]\nTo Out\n:");
    scanf(" %c",&isTrue);
    if(isTrue == 'y' || isTrue == 'Y'){
    fprintf(fptr, "the food you buy as much : %d\n", b);
    fprintf(fptr, "total price of food : %d\n", f);
    
    fclose(fptr);
    goto cashier;
    
    }

what should i do to fix this program ?


i want this fprintf(fptr, "the food you buy as much : %d\n", b);will execute and print it : "write the food you buy as much" in my notepad. but in my notepad file.txt i do not write anything before and also i do not create this file.txt name before
