Most languages require a compiler. This is because machine code consists of only 0s and 1s, which is executable. All other languages have to be translated into machine language by a compiler.
Answer:
Follows are the method definition to this question:
void Reverse_Order(struct Node* h)//defining a recursive method Reverse_Order that takes structure in parameter
{
if (h == NULL)//use if block to check head equal to null
return;//use return keyword
Reverse_Order(h->next);//call method recursively
cout<<h->data;//print data
}
Explanation:
In the above code, a recursive method "Reverse_Order" takes structure as the parameter, and inside the method, structure variable h is used that uses the if conditional statement to check the header equal to null.
In the condition is true, it will use the return keyword, and in the next step, it calls the method recursively, and print its value in the reverse order.
Answer:
The matrix theory is used by hill cipher.
Explanation:
Th technique which uses matrix theory is hill cipher technique.
Hill cipher technique is a polygraphic substitution cipher and it is based on linear algebra.
For encrypting a message in Hill Cipher technique each block of n letters is multiplied by an invertible matrix of nxn and that to against modulus 26 and for the decryption of the message, every block is multiplied by the inverse of the matrix that was used for encryption.
