eg what is 3!
algorythm: it is 3 * 2!
klimi
and what is 2! ? 2*1!
klimi
1! ? = 1 (hardcoded)
klimi
so with n it would be
n! = n * (n-1)!

Hi Guys. Please, how can I read hex value (e.g. 0E 7F) from a file and easily convert the value to binary (e.g. 111001111111)? in C++
what for binary form, I'd better just create a table of all 256 binary values of each byte value and by means of this function-table convert each byte of value to binary.
or this can be applied to semi-bytes

o.o
binary

Ok. That's a nice idea. I thought there is a built in funciton to do that

Please, what does that mean?
this is non-standard function that can be absent in the other compiler.

You can implement your own itoa

I have another challenge.
I have a plain text file with one line HEX value of example “1F AF 00 55 5D”
and I want to pick this value and then XOR it recursively to finally get one value. Meaning 1F XOR AF XOR 00 XOR 55 XOR 5D
Please, can you help me out on this?
klimi
Well you explained it

I think videos are better for getting started and books better for deep-diving into subjects
Artöm

Save your time and read a book fully
Artöm
I think videos are better for getting started and books better for deep-diving into subjects
This exact statement might be true. But I can recommend some good books but no videos, probably because books suffice for me
Artöm
Then one might be interested in discovering particular corner cases, which is good via some blogs (eg foonathan) or conferences videos (cppcon, cpp on sea)
Artöm
Thing is, such blogs and videos are completely useless for a novice
Artöm
With rare exceptions, like 104 std algos in one hour video from cppcon. Btw watch it if you havent already
Sasuke
Ok how is Let us c and C programming language by Dennis Ritchie I heared their names very often
Artöm
C programming language is C bible. Good book for documentation and language observing, also good but not the best book for learning

Best way is not to learn C, but learn c++
Ilya

Videos are best for watching stupid films like Avatar, IronMan etc.
For studying -books
