The Internet is based on a U. S. government project called . Today, the Internet is a collection of networks, tied together by common . Tier 1 networks form the Internet , a system of high-capacity routers and fiber-optic communication links arranged in a(n) topology. Networks that form the Internet are maintained by that offer access to consumers. Before data travels over the Internet, it is divided into by a protocol called , which also reassembles the data when it reaches its destination. Every device on the Internet uses an IP address . addresses are 32 bits long, whereas addresses are 128 bits long, providing billions and billions of possible addresses. Addresses are assigned by servers. IP addresses that are temporarily assigned are called addresses, whereas permanent ones are called addresses. IP addresses cannot be routed over the Internet and are usually assigned to devices within LANs. Because it is difficult to remember IP addresses , the name system allocates easy-to-remember domain names. level domains include and .edu. The servers that track these names are a vulnerable point in Internet security.

[a] create a class called âcycleâ which has two instance integer variables as properties, ânumberofwheelsâ and âweight.â create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheelsâ and âweightâ respectively. write a separate application to test the class and display its properties. note: do not change the names of the instance variables or the variables listed in the constructorâs parameter list. [b] edit your class cycle by adding a default constructor which will assign the default values of 100 to represent the numberofwheels, and 1000 to represent the weight, by invoking a call to the other constructor. modify your application created in [a] to test the class.

Writing a modular program in visual c++. i am new to this and not sure what i am missing. i am getting the following error: baddate. cpp: in function âint main()â: baddate. cpp: 50: 3: error: âelseâ without a previous âifâelsehere are the instructions and code: writing a modular program in c++in this lab, you add the input and output statements to a partially completed c++ program. when completed, the user should be able to enter a year, a month, and a day. the program then determines if the date is valid. valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31.notice that variables have been declared for you. write the simulated housekeeping() function that contains the prompts and input statements to retrieve a year, a month, and a day from the user. include the output statements in the simulated endofjob() function. the format of the output is as follows: month/day/year is a valid date. ormonth/day/year is an invalid date. execute the program entering the following date: month = 5, day = 32, year = 2014. record the output of this program. execute the program entering the following date: month = 9, day = 21, year = 2002. record the output of this /* program name: baddate. cppfunction: this program determines if a date entered by the user is valid. input: interactiveoutput: valid date is printed or user is alerted that an invalid date was entered*/#include bool validatedate(int, int, int); using namespace std; int main(){// declare variablesint year; int month; int day; const int min_year = 0, min_month = 1, max_month = 12, min_day = 1, max_day = 31; bool validdate = true; // this is the work of the housekeeping() method// get the year, then the month, then the daycout< < "enter the year"< > year; cout< < "enter the month"< > month; cout< < "enter the day"< > day; // this is the work of the detailloop() method// check to be sure date is validif(year < = min_year) // invalid yearvaliddate = false; else if (month < min_month || month > max_month) // invalid monthvaliddate = false; else if (day < min_day || day > max_day) // invalid dayvaliddate = false; // this is the work of the endofjob() method// test to see if date is valid and output date and whether it is valid or notif(validdate == true); {// output statementcout<
