Answer 1

So I wrote the exact same code a few days ago and in the output I got the string I wanted followed by a lot of characters (I don't know were from) and other times I got errors....it seemed that it alternated between these possibilities almost randomly....but now it works pretty good....anyone has an explanation please?

Answer 2

Thank you all for your help ! 👍✌🙏 It helped me a lot !The problem was indeed the conversion I suppose (not sure) but now it works just fine!😄

Answer 3

Uni
The code is working for me.
But I don't know if the algorithm is what you indend it to be.
I believe inside the for loop you what to show only a - z, A - Z , 0 - 9 and SPACE characters.
But to show characters 0 - 9 you should use:

(int)s[i] <= 57 && (int)s[i] >= 48 NOT (int)s[i] <= 9 && (int)s[i] >= 0

because 57 is the ascii value for 9 and 48 the ascii for 0.
try it.

Answer 4

Everything is fine here.
I thing the problem must be in explicit conversion that you may forget in your earlier code.
An alternative way to implement it...
