Answer:
The answer to this question is given below in the explanation section.
Explanation:
The for-loop given in the question is:
for ( j = 0; j < 10; j++ )
{
appendItem (myList, aNumber); //this loop append a number to a list myList
}
This loop starts from J variable's value zero and when J's value is less than 10, the loop iterate through its body until J's value becomes greater or equal to 10. As J's value exceed nine, the loop will get terminated.
So this loop repeats 10 times its loop body, at the 11th time, the condition becomes false and the loop will get terminated.
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.
