Answer:
I think it would be A, good luck!
Answer:
char firstLeter = name.charAt(0);
Explanation:
Consider the program below:
public class num2 {
public static void main(String[] args) {
String name = "Smith";
char firstLetter = name.charAt(0);
System.out.println(firstLetter);
}
}
In this program, A string name is defined and assigned the value "Smith".
Java's String method charAt() is called and passed the argument of index 0. This causes it to output the character S. Since this is the first letter in the String is at index 0.
The name of the programming language is “Brainfugd”
When accurately executed, the only cryptosystem known to be unbreakable is called: "One-time Pad" (Option D)
<h3>What is a Crypto System?</h3>
The one-time pad is a cryptographic approach that cannot be broken but needs the usage of a single-use pre-shared key that is not less than the message being delivered. A plaintext is coupled with a unique secret key in this manner.
It should be emphasized that in cryptography, a cryptosystem is a collection of cryptographic algorithms that are required to perform a certain security function, such as confidentiality. A cryptosystem is often composed of three algorithms: one just for key generation, one for encrypting, and one for deciphering.
