well i am writing a simple code in which the file contents of .txt file are read into an array. Next the contents of this array are copied into another array . When the contents of the new arrray are modified, the changes are also visible in the old array from which the data was copied from. This new array is then written to the same file. As a result, file data duplication is occuring......

Any help will be appreciated. Thanks.
