I have a char array of size 512 i.e
char buffer [512];
This variable after some point is modified to this
buffer [40] = '\0';
What does this assignment does to the variable? Does it initialize the first 40 char in the array to null?
It assigns only the 41st char in the array to
\0. Thus now the string consists of what the chars represent in the first 40 elements of the array i.e 0 to 39th indices (assuming there were no otherNULcharacters in any of the previous elements -Thanks Kerrek SB!!) .Hope this helps!
