Problem with string manipulation 1

[adi316]

why is it that when i do this:

output = line.substr(line.find("V&quot,line.find("/&quot) + " ";
line.erase(0,line.find("//&quot+3);
output+=line;

on this line for example:

line = 27009V234288/27008G00000000/270008// 14 2707 08 234288 032022

i get this:

output == V234288/2700 14 2707 08 234288 032022

instead of this:

V234288 14 2707 08 234288 032022

because of:

>> output = line.substr(line.find("V&quot,line.find("/&quot) + " ";

after this output is already equal to:

V234288/2700

since line.find("/&quot returns 12 so you get a 12 character string starting at "V" or 5
