Answer:
#include <iostream>
using namespace std;
void divide(int numerator, int denominator, int *quotient, int *remainder)
{
*quotient = (int)(numerator / denominator);
*remainder = numerator % denominator;
}
int main()
{
int num = 42, den = 5, quotient=0, remainder=0;
divide(num, den, "ient, &remainder);
return 0;
}
Explanation:
The exercise is for "Call by pointers". This technique is particularly useful when a variable needs to be changed by a function. In our case, the quotient and the remainder. The '&' is passing by address. Since the function is calling a pointer. We need to pass an address. This way, the function will alter the value at the address.
To sum up, in case we hadn't used pointers here, the quotient and remainder that we set to '0' would have remained zero because the function would've made copies of them, altered the copies and then DELETED the copies. When we pass by pointer, the computer goes inside the memory and changes it at the address. No new copies are made. And the value of the variable is updated.

Answer:
Its the last one, CSS and HTML are similar but like it says some prefer one over the other.
Answer:
The answer is "Option A".
Explanation:
The elliptical curve cryptography system needs much shorter keys for cryptography, and it is very powerful because of the RSA cryptography method. It is also known as a key of 1024-bit, which is in comparison is equal to the 160-bit ECC key for cryptographic, that's why other options are not correct, which is defined as follows:
- In option B, It is higher the ECC key system, that's why it's wrong.
- In option C, It is a part of the RSA system but its value doesn't match the ECC system, that's why it is wrong.
- In option D, It's valued is just double to the RSA system, that's why it is wrong.
WPA 2 stands for Wi-Fi Protected Access, version 2. It is the latest protocol that effectively protects 802.11 wireless traffic across a LAN. It belongs to the 802.11 protocol.
To provide both encryption and integrity protection, wpa2 uses aes encryption with Counter and CBC MAC (CCM) Mode.
