Kese pata chalega konsa answer galat hua ?? mera 1 galat ho gaya ?? Or quiz ya challege ke time agar koi topic na aae to kya saath saath pad lena chaheye ya challenge end hone ke baad ??

#4

int x = 5
This is signed int
u can declare unsigned int by
unsigned int x=5;

The difference among them is unsigned cant be negative and holds only poisitive nos.

yes it will take ascii value of a that is 65 .and beta is just a variable name that ll be 65 after this statment

that is your choice if you want to refer to the solution at that moment or save them for later .that wont make a difference
