Int vs signed int

Sir/Maam,
What is the difference between int and signed int?
Also since char can be interpreted as int(ASCII), does it use the unsigned property(0-255)?

hello @diganta_7777

int is also referred as signed int. i,e when we declare any variable as int then it is treated as signed int.

concept will similar for char as well but here writing char does not ensure that it will be unsigned(it may be signed or unsigned char).
read more about it from here->link1 | link2

Understood! Thanks!
