“Database” in c (not actual database, just a simple thing) [closed] Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of “Database” in c (not actual database, just a simple thing) [closed] without wasting too much if your time.

The question is published on by Tutorial Guruji team.

The main idea of the code below is to let me add, delete etc portions of the arrays so that it looks more or less like a store’s database (did this because I have no idea how to use pointers and etc). I got the thing almost figured it out, but i am having 2 big problems: The first problem is that I get a “segmentation fault (core dumped)” when I run the code and select case 1. I don’t even know what the error means so I don’t see how can I fix it. The second problem which is probably my biggest, can anybody tell me how can I store the arrays in a file in such a way that when I run the program again, the arrays won’t be empty, but will take their elements from a file, and save in the same file when I exit (that’s why I used the word database).

include stdio.h
include stdbool.h

int main()

{ bool bExit = false;
  int select, i, price[5], amount[5];
  char *name[5];


{ printf("What would you like to do ?:n");
  printf("1) Add products n");
  printf("2) Delete products n");
  printf("3) Find product by name (shows position and price) n");
  printf("4) Find product by position (shows name and price) n");
  printf("6) Display all info of all products  n");
  printf("7) Modify amount of existing product n");
  printf("8) Modify price of existing product n");
  printf("9 Exit n");
  scanf("%d", &select);
  switch (select)
    case 1:
            printf("Name: ");
            scanf("%cn", *name[i]);
            printf("Price: ");
            scanf("%dn", price[i]);
            printf("Amount: ");
            scanf("%dn", amount[i]);
    case 2:

… bla bla bla …

        printf("Good Bye n");
        bExit = true;


You do not need to use any pointer for char *name[5]. Use char name[5] instead. Probably the segmentation fault comes from this statement

scanf("%cn", *name[i]);

for the second question create a file and open it whenever you want to read/write. Something like

File *fptr=fopen("database","w");
