title: Reading variables from command line
body: <p>Hello(again :) )
  I want to know how to read something from command line like:</p>
  
  <p>OpsComp= executable
  resultados=file.txt</p>
  
  <p>$ OpsComp (23+45i)+(12+23i) resultados
  The answer is: 35+68i</p>
  
  <p>The program is supposed to read as following:
  a=23
  b=45
  c=12
  d=23
  operand=+
  make the operation and then print the operation on a file.txt(resultados)...
  I would like to know, how(when im reading b and d) could I not scan the 'i'...
  Thanks in advance,i know Im such a nuisance with my questions haha</p>
  
  <p>EDIT
  So what Im trying to do is to read (23+45i) from the command line, what im trying to ask is..how can I read the 23 as 1 variable, + as another and 45 as another(excluding the 'i and the parenthesis')
  from the command line</p>
