Lottery number generator design a program that generates a 7-digit lottery number. the program should have an integer array with 7 elements. write a loop that steps through the array, randomly generating a number in the range of 0 through 9 for each element. then ask the user to input 7 numbers into another array. display the lottery numbers and the user’s chosen numbers. then display if the user is a lottery winner or should try again. continue this loop until the user types in ‘x’ to quit.

Explanation:

Using c++ rand function generate a random number between 0-9.

Formula for random number is rand (max-min +1)+min.

Run this in a loop for 7 time and store each number to an array index in sys array which is for system generated number.

now using string take input from user and check if input is x close program else use stringstream to parse input string to int and store it in user array. Stringstream is a cpp header file used for parsing and handling of strin g inputs. Run this program in loop for 7 times.

Now create a function of type boolean denoted by "bool". This will take both arr as parameter and check if both are equal or not. It compares eac index of user array against each index of sys array and if both values are not equal returns false.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
