What exactly happens, in terms of memory, when i declare something like: char arr[4];
How many bytes are reserved for arr?
How is null string accommodated when I 'strcpy' a string of length 4 in arr?
I was writing a socket program, and when I tried to suffix NULL at arr[4] (i.e. the 5th memory location), I ended up replacing the values of some other variables of the program (overflow) and got into a big time mess.
Any descriptions of how compilers (gcc is what I used) manage memory?
