i am trying to compare the filename given by user with the array of strings.when i run this code i get error as:
In function `add_record':
syntax error before ']' token

also,even if i remove the code from 'start' to 'stop' i get error as:
i:\gw\lib\crt2.o(.text+0x8) In function _mingw_CRTStartup':
[Linker error] undefined reference to__dyn_tls_init_callback'
[Linker error] undefined reference to `__cpu_features_init'
i:\gw\lib\crt2.o(.text+0x8) ld returned 1 exit status

Please help me.Thank you!

void add_record()
{
 FILE *fp;
 char filename[25],fname_check[NO_OF_FILE][25];
 char tester;
 int i;

 printf("Type the name of the file you want to store the record in : ");
 scanf("%s",filename);
 //start
 for(i=0;i<sizeof(fname_check);i++)
 {
                                   if(strcmp(fname_check[i][],filename) == 0) printf("File already exists!\n");
                                   break;
                                   }
 printf("The file will be overwritten if you enter the same name.....\n");                                  

 printf("Type the name of the file you want to store the record in : ");
 scanf("%s",filename);
   //end                              

 fp = fopen(filename,"w");
 if(fp == NULL)
 {
       printf("Sorry,File cannot be opened!");
       getch();
       exit(0);
       }

 while(1)
 {
         fflush(stdin);
  printf("\nEnter name : ");
  gets(pro.name);
  printf("Enter age : ");
  scanf("%d",&pro.age);
  printf("Enter gender : ");
  gets(pro.gender);
  printf("Enter phone : ");
  scanf("%d",&pro.phone);
  printf("Enter email : ");
  gets(pro.email);
  printf("Enter location : ");
  gets(pro.location);
  printf("Enter bio : ");
  gets(pro.bio);

  printf("If you want to add more records press any key... or press ESC key... ");
  tester = getche();
  if(tester == 27) break;
 }
 fclose(fp);

}enter code here

fname_check[i][] isn't valid. All you need is fname_check[i] which is a string.

Also, you have to loop until i < sizeof(fname_check)\sizeof(fname_check[0]), since sizeof(fname_check) will give the total size of the array in bytes.
