The computer industry is changing, and 64-bit technology is the next,
inevitable step.
Look at sample.
int main(int, const char **) {
int a = -2;
unsigned b = 1;
int array[5] = { 1, 2, 3, 4, 5 };
int *ptr = array + 3;
ptr = ptr + (a + b); //Invalid pointer value on 64-bit platform
printf("%i\n", *ptr); //Access violation on 64-bit platform
return 0;
}
Do you know why this code does not work on 64-bit system? Do you
assured, what no similar errors founds in your code? Do you know other
typical errors reduce to down state C++ code on 64-bit platforms? If is
not present then visit site

On this site you can find plenty information, devoted to programming of
64-bit systems. And also static analyzer Viva64 for detects multitude
64-bit portability issues.
