This feature allows developers to selectively enable additional functionality to improve security and reliability in their programs. Copying Partial ArraysThis example shows how to copy a portion of an array using memcpy. partial_copy.c #include <stdio.h> #include <string.h> int main() { int ...
This proves that a new object "b" is created which is an actual copy of "a". If we change an element in "a", it is not reflected in "b". a[2]=10print(a,b) It will produce the followingoutput− array('i', [110, 220, 10, 440, 550]) array('i', [110, 220, 330, ...

The 1.4.2 server VM throws a bad ArrayIndexOutOfBoundsException in the copying loop (similar to the previously fixed problem - 4629512 ). The test case below exits because of the ArrayIndexOutOfBoundsException inside the copying loop on 32 bit solaris in the server mode. Same test case run...
