Andrea wants to to install a new internet connection . she eants to use the fastest one she can find . what are the maximum spee

DaniilM [7]

A dial-up access connection supports a speed up to 56kbps, whereas an ISDN line goes up to 1.9Mbps. A DSL connection can support a maximum of 20mbps. Internet access speed through cable TV is capable of up to 1000mbps.

Dial-up connection is by far the slowest of all known internet connections. The maximum speeds that can be supported by this connection are about 56Kbps. Use of this type of connection requires a separate phone line. In an ISDN type of connection, the maximum speeds depend on where in the world you are. The highest to have ever been recorded is an ISDN E1 line that has a combined data rate of 1.9 Mbit/s. Speeds transmitted through DSL are generally the same ones that are transmitted through cable internet and satellite connection. You can expect DSL speeds of 512Kbps to a max of 20Mbps. The cable internet is a broadband internet access and the highest bit rates of cable internet can go be up to 1GBPS which is equivalent to 1000Mbps.

Create a conditional expression that evaluates to string "negative" if userVal is less than 0, and "non-negative" otherwise. Ex:

Goryan [66]

Answer:

PROGRAMMING APPROACH:

Define the necessary header file using namespace.
Define the main() method.
Declare variable inside the function().
Print result.

Explanation:

Required C++ Code:

#include<iostream>

#include<string>

using namespace std;

int main()

{

string condStr;

int userVal;

cin>>userVal;

condStr=(userVal<0)?("negative"):("non-negative");

cout<<userVal<< " is "<< condStr <<"."<<endl;

}

OUTPUT:

-2

-2 is negative.
