    Question Help me debug some part in my program

    hello, this coding works and run perfectly. just there are some minor mistakes while searching for the contact. the program will keep on print CONTACT RECORD IS NOT FOUND multiple times until the contact list arrangement is same to the list. Can someone show me the better coding for that part so that the contact will directly appear for the name searched without having to see the contact is not found. Please!


    Code:
    #include<stdio.h>
    //#include<conio.h>
    #include<string.h>
    #include<stdlib.h>
    //#include<windows.h>

        long int mble_no;
        char sex[8];
        char mail[100];
        char ic_no[20];
    
    
        };
    void menu();
    void got();

    Well the nicely formatted code here has been turned back into dog food.

    > the program will keep on print CONTACT RECORD IS NOT FOUND multiple times until the contact list arrangement is same to the list.
    Because you can't tell from your CRAP indentation that the print is INSIDE the loop.

    Code:
      while (fread(&p, sizeof(p), 1, f) == 1) {
        if (strcmp(strupr(p.name), strupr(name)) == 0) {
          count++;
          system("cls");
          printf("\n\n\n\tDetail Information About: %s", name);
          printf
              ("\n\n\tName : %s\n\n\tAddress : %s\n\n\tFather's Name : %s\n\n\tMother's Name : %s\n\n\tMobile No (+60) : %ld\n\n\tGender : s\n\n\tE-mail : %s\n\n\tIC No:%s",
               p.name, p.address, p.father_name, p.mother_name, p.mble_no, p.sex, p.mail, p.ic_no);
        } else
          //!! yes Dorothy, this happens on every node that doesn't match
          printf("\n\n\tERROR: CONTACT FOR NAME %s IS NOT FOUND!", name);
      }
    It should be outside the loop, maybe like
    Code:
      while (fread(&p, sizeof(p), 1, f) == 1) {
        if (strcmp(strupr(p.name), strupr(name)) == 0) {
          count++;
          system("cls");
          printf("\n\n\n\tDetail Information About: %s", name);
          printf
              ("\n\n\tName : %s\n\n\tAddress : %s\n\n\tFather's Name : %s\n\n\tMother's Name : %s\n\n\tMobile No (+60) : %ld\n\n\tGender : s\n\n\tE-mail : %s\n\n\tIC No:%s",
               p.name, p.address, p.father_name, p.mother_name, p.mble_no, p.sex, p.mail, p.ic_no);
        }
      }
      if ( count == 0 ) {
          printf("\n\n\tERROR: CONTACT FOR NAME %s IS NOT FOUND!", name);
      }
    You haven't removed any of those fflush(stdin) calls.
    Why fflush(stdin) is wrong - Cprogramming.com

    You're still calling menu() recursively instead of using a while loop, or just simply returning.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I am very sorry, but can you show me on how to return to main menu using while loop instead of calling it recursion? I dont want the user to exit and the run again just to go to the main menu again. I am newbie and not very understand in this programming courses. This is only for my elective subject and we need to debug the source code as our final project. Please help me anyone otherwise i will fail for this course. T_T
    Below is my latest code. Sorry for causing inconvenience.

    Code:
    #include<stdio.h>

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
