To convert a number to a 16-digit string, we can call sprintf, but the standard library of C does not provide a function that converts a hexadecimal string number to an integer number. I've written a feature that can be implemented and optimized as much as possible. (Currently this function only supports 32-bit)/* input hex string, format:0xaa111 or AA111 or abc11/int ahextoi (char* p) {int n = 0; char* q = p; /* Reach's Tail/while (*Q)
