thank you very much can you tell me text file can contain integers ? and what will be the path of text file?

The default location of the file will be in the current project directory.

As to other data formats the answer is there are two versions of the memory access function: $readmemb expects a binary string format, and $readmemh expects a hex string format. There is no version that will expect decimal strings, which I assume is what you mean by 'integer' format.
