I think you missed the point of the exercise...
To convert a numeric string to an array of integers...

this is an example of what I want...

user inputs 14364 as a string (scanf("%s",number))

The number then gets stored in an array like this

int number[5];

number[0]=1
number[1]=4
number[2]=3
number[3]=6
number[4]=4

Nope, don't think so.

One suggestion given, in dealing with "magic numbers" is to give them meaningful
names for example, using a #define statement.

I believe the above is the correct concept, not to be taken lightly.

Yep... #define is the way to do things in that case.
