Answer:
Open a text-based editor like Microsoft word, notepad, libraoffice, etc, type the name of the super hero on the first field and the main power on the second field. Then click on the file menu or press ctrl-s and save file as superheroes.dat.
Explanation:
The file extension 'dat' is used to hold data for programs, for easy access. The file above holds data in fields separated by a space and has multiple records.
Answer:
<em>#include <iostream></em>
<em>using namespace std;</em>
<em>int main()</em>
<em>{</em>
<em> int myNewAge;</em>
<em> int myCurrentAge = 29;</em>
<em> int currentYear = 2020;</em>
<em> </em>
<em>myNewAge = myCurrentAge+(2050-currentYear);</em>
<em />
<em>cout<<"My Current Age is "<<myCurrentAge<<". I will be "<<myNewAge<<" in 2050"<<endl;</em>
<em> return 0;</em>
<em>}</em>
Explanation:
The program is written in C++ language as required. firstly, we declare the three variables:
<em> </em><em>int myNewAge;</em>
<em> int myCurrentAge = 29;</em>
<em> int currentYear = 2020;</em>
Then we calculate the new age as: <em>myNewAge = myCurrentAge+(2050-currentYear);</em>
Using multiple cout operators (<em> </em><<) we display the output nicely as required by the question with this statement
<em>cout<<"My Current Age is "<<myCurrentAge<<". I will be "<<myNewAge<<" in 2050"<<endl;</em>
Answer: Well known ports
Explanation:
DHCP server transmit the response to the dynamic host configuration server protocol (DHCP) clients. DHCP default port is 67 and its port number is greater than the user data-gram specific port.
FTP server has its default listen at port 21 and file transition protocol(FTP) uses two transmission control protocol(TCP) connection for communication in the network. FTP passes information in port number 21, which is only used to send control information.
Well known port are use to identify the service of network on the public internet and private internet network. Therefore, port 21 and 67 are the well known ports.
