Thanks Corona688!
I did not forget your advice on fgets() + sscanf() in C. Switched from there I was hoping to get similar advice in C++ so that I used "best practice". I am aware this is about very basic I/O stream that I'm still struggling with.
Spend more time on this, and found out my confusion also related to this line of the stackoverflow code, which seems wrong to me:
My question seems answered.
Thanks again!

Reason: Formating to get better view
Hi Folks,
I have been trying to create a script wherein after it reads a certain number of data, it will pause and ask the user if he wants to continue or not. However, it seems that when it is supposed to read the user's answer, the script will go into a loop. What is wrong with my script here?... (7 Replies)

numrange
NUMRANGE(1) User Contributed Perl Documentation NUMRANGE(1)NAME
numrange - Print out a range of numbers for use in for loops and such.
SYNOPSIS
numrange [-dhV] /<expression>/
DESCRIPTION
numrange will print out a list of numbers based on an expression that you specify. This is useful for making a list of numbers for use in
for loops and so on. Ranges are inclusive. Ranges of numbers are specified using the .. operator, like this /20..50/, which means all
integers from 20 to 50 inclusive. More complex expressions can be generated using the commas and the 'i' increment operator.
OPTIONS -e <set> Exclude the <set> of numbers from the range output. <set>
is a set of numbers separated by commas.
-n <n> Use <n> as the separator between numbers. By default, it
will use a space. Use '
' or \n for a newline character or
use the -N option.
-N Just a quick option for using a newline as the separator.
-h Help: You're looking at it.
-V Increase verbosity.
-d Debug mode. For developers
EXAMPLES
All numbers from 1 to 10.
$ numrange /1..10/
1 2 3 4 5 6 7 8 9 10
From 10 to 1. Counting down.
$ numrange /10..1/
10 9 8 7 6 5 4 3 2 1
From 1 to 10 and from 15 to 20.
$ numrange /1..10,15..20/
1 2 3 4 5 6 7 8 9 10 15 16 17 18 19 20
Even numbers from 0 to 10
$ numrange /0..10i2/
0 2 4 6 8 10
Odd numbers. Notice the starting number in the range expression.
$ numrange /1..10i2/
1 3 5 7 9
Factors of 3 between 99 and 120.
$ numrange /99..120i3/
99 102 105 108 111 114 117 120
Decimal numbers
$ numrange /1.1..2.5i0.1/
1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2 2.1 2.2 2.3 2.4 2.5
And negative numbers too.
$ numrange /1.0..-2.0i0.3/
1 0.7 0.4 0.1 -0.2 -0.5 -0.8 -1.1 -1.4 -1.7 -2
You can also pad numbers when you are counting up. This is
a trick of how the Perl programming language deals with ranges:
$ numrange /01..15/
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15
BUGS
Even though you can do zero padding on simple ranges, like 001..100, it will not pad zeros on complex ranges like 001..100i2, or for
counting downwards.
