write a c program to multiply a 50 digit number with a 4 digit number using array?

Answer 1

sounds like you need to go back to MS DOS. representing a mathematical calculation like that in integer format will take up the whole screen. Otherwise start using powers and forget the writing of the program: use a calculator.

Answer 2

I am not in the habit of actually writing out solutions to what appears like homework, something like this isn't too hard. A couple arrays, a few loops and you can do it quite easily. Experiment.

Answer 3

Just do it in Python!
