A char in C is already a number (the character's ASCII code), no conversion required.
@kevin001 If you want to convert the char to int and a character '1' provides a ascii number that's not 1, you need to remove the offset '0' to realign it to count from 0-9.
you should change char* to char, right now numberstring is an array of pointers – josefx Jun 1 '12 at 9:10.
Why don't I have to convert int to char with getchar() when reading into a buffer in C?
Then your char could be said to be 'converted'.

What about the other char types, wchar_t, char16_t, and char32_t?
How many times have you had a need to convert between variable types such as converting character to numeric or numeric to character? For example, what if you have a character variable with numeric values but you need to perform some calculations?
This will inspect the command line, convert each argument to the appropriate type and then invoke the appropriate action. In most cases, this means a simple Namespace object will be built up from attributes parsed out of the command line
