Reading A File In As An Argument and Other
Hello,
I have two questions:
One, how do you accept and read a text file called "input.txt" as an argument? I believe the environment being used is a Unix environment.
Two, if the above file contents are:
20
2 20
10 8
4 26
20 7
3 11
13 3
18 5
11 9
1 6
14 10
14 20
8 3
5 26
12 19
6 11
7 14
0 8
19 11
15 9
14 22
How would I write the numbers in, after 20, into two separate arrays. So, in line two, "2" would go into one array while "20" would go into another.

2. For the first line you would read in the single value by itself
lineIn >> X;
for the rest of the lines you would read it in
lineIn >> X; lineIn >> Y;
If you read it in as a string you would break it apart based on where the space is at
There are a couple ways to do that
might work and then use string.erase and then convert to a int if that is your desire.

May have taken awhile for me to reply, but thank you. This helped a lot with my next project.
