HI,
Whats the meaning of this code:-
char buff[100];
memset(buff, 'A' , 100);
sometimes we can place hex value in
place of 'A' like 0x90c
but how this code function actually.
thanks in advance
I am not saying 'A' is replaced by
0x90c but i am saying we can
place any hex value as per
requirement in place of 'A'
and I want brief explanation.
An explanation would probably be that 'char' is a type that
can store values (of a certain range). 'A' represents a value
that can be stored in a 'char' object. So does 0 and any
other integral that can be converted to 'char'. The hex
notation is just a way of representing the value. For example,
in ASCII, 0x41 is the hex equivalent of 'A' (the capital form
of the first letter of the Latin alphabet). 65 is the decimal
equivalent of 0x41 (and of 'A'). 0101 is the octal equivalent.
RTFM on memset. Then build a minimal program with your code
and run it under a debugger, looking at the elements of the
array 'buff' as you step through your code.
