I have a string. $a="2A2B2C". The values of A,B,C are stored in an array @p=(1.5,2.5,3.5). The result of $a should be like this: (AA)*(50/100) (BB)*(55/100) (CC)*(60/100). The values of A,B,C should be repeated according to the adjacent number before that character. I may be wrong somewhere in the coding. The answer should be 28.4238 where as i am getting 2.165625. Here is the code which i used:
$a="2A2B2C"; @p=(1.5,2.5,3.5); #print substr($a,0,1); #print "\n"; $b=length($a); print "$b\n"; for($i=0;$i<$b;$i++){ $a=~s/(\d+)(.)/$2 x $1/ge; } #print $a; for(1..$b) { if(1==$_) { $c=substr($a,0,1); $r1=$p[0]*(50/100); print $r1; } elsif(2==$_) { $c2=substr($a,1,1); #print "\n$c"; } elsif(3==$_) { $c3=substr($a,2,1); $r2=$p[1]*(55/100); print "\n$r2"; } elsif(4==$_) { $c4=substr($a,3,1); #print "\n$c"; } elsif(5==$_) { $c5=substr($a,3,1); $r3=$p[2]*(60/100); #print "\n$r3"; } elsif(6==$_) { $c6=substr($a,5,1); #print "\n$c"; } } $answer=$r1*$r2*$r3; print "\n$answer";

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
