Question

1. (20 points) Write a main function that performs the following

operations:

a.) Prompts the user to input the names of 3 files: two input files and

an output file.

b.) Reads in the two input files line by line and compares the two

lines.

c.) For each line in the inputs, the output should have the line number,

a colon (':'), and either "OK" if the lines match or "DIFF" if the lines

are different.

The input files may be of different lengths.

Note that:

- You will NEED to use the facilities presented in Chapter 10

(specifically, getline(...)) to complete this assignment. If you use the

>> operator, it will ignore whitespace (so your program will likely

report "a a" and "aa" as being the same.

- Your program should be case-sensitive, so you do NOT need to worry

about converting text to lowercase or uppercase.

For example:

input1:

abc

def

g h i

input2:

abc

DEf

ghi

uub

output:

1:OK

2:DIFF

3:DIFF

4:DIFF

#include "std_lib_facilities_3.h" int main() { string file1; string file2; string out_file; { cout
