Answer:
Following are the program in c++ language
#include <iostream> // header file
using namespace std;// namespace
int main() // main function
{
int num; // variable declaration
long int f=1; // variable declaration
do
{
cout<<"Enter the Positive value:";
cin>>num;
} while(num<0); // i check whether number is non negative or not
while(num>0) // iterating over the loop
{
f=f*num; // calculate the factorial
num--; // decrement the value of num by 1
}
cout<<" factorial is :"<<f; // display the factorial .
return 0;
}
Output:
Enter the Positive value:7
factorial is :5040
Explanation:
Following are the description of the program .
- Read the input by user in the "num" variable of "int" type..
- The do-while will check the enter number is nonnegative number.
- While(n>0) loop is calculating the factorial in the "f" variable .
- Finally display the factorial .
Answer: The advantage of the optical fibre over the other medium of the communication are as follows:-
- The bandwidth of the optical fibre is comparatively higher than the other communication media
- The security in regard with the loss of data can be tracked easily as compared with other copper wire medium of communication.Thus, the security system of optical fibre is more reliable.
- The capacity of the fibre and the transmission power is also high as compared with other media of the communication such as copper wires,etc.
- The optical fibre is less space consuming than other communication medium.

Answer:
Option C is the correct answer for the above question.
Explanation:
The ciphertext is a text which is formed from an original text and can be called a duplicate text which has no meaning for the other user. This can be formed with the help of encryption technology. Encryption technology is a technology that uses some mythology to convert the original data into other text data (which is also called a ciphertext) because no one can able to hack the data.
The above question asked about the term which is called for the text when it is converted from original data. That text is known as ciphertext which is described above and it is stated from option c. Hence option c is the correct answer while the other is not because--
- Option 'a' refers to the public key which is used to encrypt the data.
- Option b refers to the private key which is also used for encryption.
- Option d refers to the sniffer which is not the correct answer.
