Answer 1

hello sam99. I am not familliar with the c language. however i do know a little bit of python. its possible to have users input numbers, and have the program convert it. so i would recommend python for doing somthing like that. i could be wrong since i do not know and C language what so ever. hope this helped. :)

Treat the prompt and enter code as it's own little program.

The fun part is breaking down the number. You need to know whether you're dealing with thousands, hundreds, tens or ones. It's fairly simple to write a recursive function to find the exponent of your most significant digit, or you could do it with if/else if/else statements.

Just output an M for each thousand.

The digits always break down into X, IX, VIII, VII, VI, V, IV, III, II, I. The X and V can be C and L or M and D, depending on the magnitude of the digit. So you could make a table for each digit describing the 5's and 1's involved, and then depending on the magnitude, output the appropriate number of D's, L's, V's and C's, X's, I's.
