body: <p>i am trying to convert array object into string but still it is returning address of object.
  it is returning - <strong>0x5e1e370</strong>
  but should return some string value .</p>
  
  <pre><code>NSMutableArray *arrStudents = [pillboxDb getStudentRecords];
  NSString *strHow = [arrStudents objectAtIndex:0];
  NSLog(@"%@",strHow);
  </code></pre>
  
  <p>Here is the code for getStudentRecords</p>
  
  <pre><code>+(NSMutableArray*)getStudentRecords{
  
  NSArray *arrDocPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *strDestPath = [NSString stringWithFormat:@"%@/samplepillbox1.sqlite",[arrDocPath objectAtIndex:0]];
  NSMutableArray *arrStudents = [[NSMutableArray alloc]init];
  sqlite3 *db;
  if(sqlite3_open([strDestPath UTF8String], &amp;db)==SQLITE_OK)
  {
  
      NSString *query = @"select * from doctor_master";
      void* v;
      char* err_msg;
      sqlite3_stmt *studentStmt;
  
      if(sqlite3_prepare_v2(db, [query UTF8String], -1, &amp;studentStmt, &amp;err_msg)==SQLITE_OK)
      {
          while (sqlite3_step(studentStmt)==SQLITE_ROW) {
  
              int sno = sqlite3_column_int(studentStmt, 0);
              NSString *sname = [NSString stringWithUTF8String: sqlite3_column_text(studentStmt, 1)];
              //float marks = sqlite3_column_double(studentStmt, 2);
  
              pillbox *st = [[pillbox alloc]init];
              st.Din = sno;
              st.Name = sname;
  
              [arrStudents addObject:st];
          }
  
      }
