I am coding lua scripts with three string concatenation,but the result is not what I want，the result is a weird string
a = 'username=' ..usermap[counter%table.getn(usermap)]
b = '&password=123456'
c = a..b
print(a)
print(b)
print(c)
the output result is:
username=abcd1999999
&password=123456
&password=1234569999
I expect c output:
username=abcd1999999&password=123456

Looks like the strings in your usermap have carriage returns (`r') in them.

Also, Lua tables are 1-indexed, so your modulo will not give the expected result and nil on the first (remove 1 from getn, add 1 after modulo)

I got your expected result in my IDE using 5.3, 5.2 and 5.1. I substitutedusermap[counter%table.getn(usermap)]withusername=abcd1999999as i did not have the code for the structure.
