Currency convertion and future value conversion

[Zeromos]

Cant get this to run, its supposed to convert dollars to euros,pesos and yen and use the same amount of dollars entered to calculate its future value.
im getting this error>> 144:1: error: expected unqualified-id before '{' token

First, please use code tags. See http://www.cplusplus.com/articles/jEywvCM9/
(If you had used tags, we might see where the line 144 is.)

Second. You have a lot of tedious and unnecessary repetition. Consider this:

void convert( float amount, float rate, const std::string & name )
{
  std::cout << "The dollars entred are converted to\n";
  std::cout << rate * amount << ' ' << name << '\n';
}
