This function would not write on the console.

Jaddo19:
Try it out

nsimageorge:
It didn't work. Except you are testing your code in a non-popular environment.
To the best of my knowledge, the javascript console can be accessed only through the console object.

write a program that'Ll prompt user to enter 0 to conver from usd to rmb. And 1 to convert from rmb to usd
Like this
Enter exchange rate from $ to rmb-6.81
Enter 0 to convert usd-rmb and 1 vice versa
Enter dollar amount-$100
$100 is 681.0yuan
Enter the exchange rate from $-rmb-Enter 0 to convert usd-rmb and 1 vice versa
Enter the rmb amount-10000
10000yuan is $1468.43
