Please I need this answers ASAP for Linux Class.

Lab Writeup

Explain what the following diff outputs and patch commands would do.

Chunk 1:

1c1 < // this is the original file --- > // this is the new file

Chunk 2:

2a3 > // Additional comments added to the new file

Chunk 3:

7a9,11 > class Time; // forward reference > istream &operator >> (istream &, Time &); >

Chunk 4:

8a13 > friend ostream &operator<<(ostream &, const Time &);

Chunk 5:

13a19 > Time &setTime( const Time & ); // set Time object

Chunk 6:

25d30 < void printMilitary() const; // print military time

7. Assume you had the following output in a file called diff_file:

--- hw4_2.cpp 2009-11-18 14:54:47.000000000 -0800 +++ hw4_2b.cpp 2009-11-18 14:56:04.000000000 -0800 @@ -14,18 +14,14 @@ int size; // Current number of elements in nums double avg, stdev; - cout << "How many integers do you wish to enter?

What would the command patch -p0 ?
