Explanation / Answer

29) Answer : 5

Explanation: File already contains 60 integer, we have opened the file using w+ mode . w+ mode deletes the content of the file. When we write buffer to it so total data and size will become 5

30) Answer : 65

Explanation: File already contains 60 integer, we have opened the file using r+ mode. r++ mode doesnt delete the content of file . So file data will be appended to next 60 integers and we write buffer to it so total data and size will become 65
