splitting numbers into separate digits

[sureshjayaraman]

a c++ program to accept a value and split it digit by digit and display in name

eg:123
>one two three

[weaknessforcats]

So 123/100 is 1

Subtract 100 from 123 to get 23

23/10 is 2

Subtract 2* 10 from 23 to get 3.

That's the algorithm. All you have to now is code it up.

another idea would be to read the value into a string, use an array to hold the written representation of each digit, and loop through the input.

string num_text[] = { "zero", "one", "two", ... };
 

num_text[input.at(loop_index_pos) - '0'];

Another way which I think closely mirrors weaknessforcats algorithm is:
1.)get the number with cin>>
2.)mod(%) the number with 10 to get the least significant digit as the remainder and store it somewhere.
3.)divide the number by 10 to lop that digit.
4.)repeat 2.) and 3.) until digits exhausted
5.)your store is now full of individual digits.
6.)fill a container (array or vector) with the ten digit names e.g."zero","one",..."nine".
7.)set up a loop to match each digit with its name and print it.

There are lots more. These are the first few that I found by searching for "number words hundred". The search bar is at the top-right corner of the Bytes page.
