Let's see if it works First Message We should see the following
in the console output The agile brown fox jumped over the lazy
dog. success! But wait. Since we know there is a terminator at
the end of the first message and the terminator marks where the
string ends why isn't the output simply Empower your team. Lead
the industry. Subscribe to a library of online courses and
digital learning tools for your organization via . This is
thanks to the magic of functions. This function is specifically
designed to handle terminating strings taking into account the
fact that multiple strings each have their own terminating
character.
So when it puts in a new source string it automatically removes
the terminator from the target. How convenient! Safe but there's
a problem. Functions work great when Phone Number List

the programmer does everything
correctly but what happens when there are multiple people on the

On modern computers this can cause a crash in the worst case
scenario. But on less secure systems this could result in
overwriting memory that doesn't belong to your application!
and in fact has been the case for many security breaches in the
past. Realizing that this was a real problem the standards
committee added an updated function to the standard library The
function works exactly like except that it has an extra
parameter representing the number of characters to copy.
