Decimal to Hex in C++

Question

I have created this program that gets a number and a base, then prints the number in the wanted value.
It works well for bases of 2 to 9, but when it wants to convert a decimal number to a base bigger than 9, like 11, or 16, it prints the ASKII value of the assigned character, how can I fix it?

Answer 1

The Geek ,

you can use this:
char z[16]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};

but this is better:
char z[]="0123456789ABCDEF";

Answer 3

You can easily convert int to hex with stringstream.

If you don't need to save the var it's even easier.

Answer 4

Someone mentioned the importance of finding your own solutions first if possible then learning to refine later to me just a few days ago (the order of comments does not show acurately):

"That is the ideal way to learn.🤓 Use what you what you have, apply what you know. Refinement comes later. Making it work is the goal."

Good advice I think.

Thank you both. SoloProg and Scott D

Your codes are very interesting... I found a way to fix my error, but your solutions are easier than mine.

Scott D thank you. :)

Answer 7

SoloProg
Thank you so much.

Why the second one is better?

Answer 8

The Geek ,

Because your code was longer so the second one works just as well but also shorter and more readable.

Aha, got it, thanks.
