Concatenate string from text file

Hi

mY files paths are defined as :


Code:
//sbase = 'D:\data\sample_AMC\fasta_files\';
sbase2 = 'D:\data\sample_AMC\fasta_files\results\';
snameprefix = 'orig_ind';
snameprefix3 = 'results_ind';

...
const string filname = sbase + snameprefix  + snamesuffix;
const string resultsname_ = sbase2 + snameprefix3  + snamesuffix;

This concatenation works perfectly fine when i have to manually defines the samplesnames


However now I have 98 such samples names to work with.This implies I have to keep updating my sbase and sbase2 98 times.

If my sample name changes from sample_AMC to sampleABC_123 then I have to update the path manuallyto
Code:
sbase = 'D:\data\sampleABC_123\fasta_files\';
sbase2 = 'D:\data\sampleABC_123\fasta_files\results\';


In order to make it easier,I saved all my 98 samplename entries in a text file.


text file looks like this
sample_AMC
sampleABC_123
sampeBMC
sampleQWE

Is there a way I could read string entries line by line from a text file using c++ and concatenate it to sbase and sbase2?

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
