How do printf, scanf, cout, cin, work(want to know deeply)?

Answer 1

Thanks for the reference

Answer 2

I think c++ is made by the basic language like assembly language and assembly language is connected with the electronic device.So working of c++ should be related to the assembly language or other language not with the electronic device.

Programmer -> text editor -> compiler - > Assembly language -> Binary codes -> Operating System -> Hardware Chip
# programmer writes the instructions in text editor then it executed by compiler
# Compiler Converts into machine codes (Binary Codes)
# OS is responsible for to feed the software to right hardware
(Line by line instructions that converted into binary Codes
Then line by line instruction stored into ROM
ROM - Read only memory (storage purpose)
Then it's executed via RAM
RAM-Random access Memory
(Temporary storage device has capable to execution purpose)
Then executed by processor (combination of IC's)
After that it returns the result (instruction has error or not)
To the Display port or other output ports
If u want learn more deeply study about Digital VLSI design

Fine👍

Answer 5

Learn about electronic device
# Resister
# Capacitor
# Transistors
# IC's
# Pulse generators and modulators
# Ram & Rom
# Finally VLSI and Machine learning
Then you get the logic behind this 🤗
