How do you multiply/modify a variable so that the value it displays is twice what the user entered?
I am asking the user to input an age and I want the output to show an age that is two times what the user entered. Can anyone please help?

You need to make sure you receive the input as a numeric data type, or you need to convert the string input to a double (that is a hint about which function you should be using). Currently you're multiplying the separate characters in the char array, so ['2'*2 '0'*2].
