It turns out that Winsock 2 provides the inet_addr() function, which simply returns the equivalent decimal value for the address. #include <stdio.h> #include <winsock2.h> int main(void) { char* pAddr = “192.168.0.1”; unsigned long value = inet_addr(pAddr); if (value == INADDR_NONE) printf(“Invalid format of IP address”); else printf(“Decimal representation of %s is: %lu”, pAddr, value); return … Read more
You can use List<List<String>> instead for example : List<List<String>> arrList = new ArrayList<>(); for (int i = 0; i < 5; i++) { List<String> arr = new ArrayList<>(); arr.add(“a” + i); arr.add(“b” + i); arr.add(“c” + i); arrList.add(arr); } System.out.println(arrList); Output [[a0, b0, c0], [a1, b1, c1], [a2, b2, c2], [a3, b3, c3], [a4, b4, … Read more

a=b; After this assignment a points to the same location as b (“Secure Coding”). You have lost any reference to the initial location pointed by a, so essentially “Insecure Coding” is garbage that cannot be freed. Another issue is that you are freeing the same pointer twice. After the first free you no longer own … Read more

Your addressing, and memory management is just plain… off. Firstly, there’s absolutely no reason to create a singleton for this, but that’s beside the point here. Secondly, when declaring properties, (atomic, assign) is defaulted to if not otherwise specified, which means your string: @property (nonatomic)NSString *passedValue; is weak sauce, ripe for deallocation and destruction at … Read more
