quick guide

This function concatenates the source string at the
end of the target string. For example "Bombay" and "Nagpur"
on concatenation would result into a string "BombayNagpur".
Here is an example of strcat() at work.

main()
{
strcat(target, source);
printf("\n source string = %s", source);
printf("\n target string = %s", target);
}

output:source string = Folks
target string = HelloFolks

Note that the target string has been made big enough
to hold the final string .
