Question

I have a following array and a printf() stament,

char array[1024] = "My Message: 0x7ffff6be9600";
printf("%.14s", strstr(array, " 0x") + 1);

The output of above printf() is 0x7ffff6be9600,
can we store it into a unsigned long variable?

Answer 1

Since you tagged this as C++, see istringstream.

using std::istringstream;
const char source_text[] =  "0x7ffff6be9600";
unsigned long value;
istringstream input(source_text);
input >> hex >> value;
