strange error in compiling small c++ code [closed]

Question

I tried to compile the following code, but it fails:

#include <iostream>

    int main(){
    double conveter, temp=25;

    conveter = (temp – 32.0) * 5.0/9.0;
    std::cout<<conveter;
        return 0;
    }

with this error:

error C2146: syntax error : missing ')' before identifier '–'

Any advise please?

Answer 1

Wrong minus sign, type the minus sign again, then it works perfectly. Unicode...

You – -> me -

Answer 2

You've somehow ended up with a Unicode "en dash" character instead of an ASCII -.

Make sure you're using a plain text editor not a word processor; delete and retype the dash; and be careful where you copy and paste code from.
