<u>Networks were originally used as a government weapon 61 years ago</u> to <u>communicate information</u> such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.
<u>Our internet today is capable of communicating with bilions of computers.</u> This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, <u>the internet is just a large network of networks that are connected through very fast radiowaves</u>. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, <u>B</u><u> would be incorrect. </u>
The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, <u>A</u><u> would not be correct.</u>
As described already, the network was a selection of computers used to communicate information to each other. <u>C </u><u>would not be correct </u>as it states that there is only one computer being used.


Answer:
#include <iostream>
using namespace std;
int main()
{
int arr[]={3,-9,9,33,-4,-5, 100,4,-23};
int pos;
int n=sizeof(arr)/sizeof(arr[0]);
for(int i=0;i<n;i++){
if(arr[i]>=0){
pos++;
}
}
cout<<"Number of positive integers is "<<pos<<endl;
return 0;
}
Explanation:
create the main function in the c++ programming and declare the array with the element. Then, store the size of array by using the formula:
int n=sizeof(arr)/sizeof(arr[0]);
after that, take a for loop for traversing the array and then check condition for positive element using if statement,
condition is array element greater than or equal to zero.
if condition true then increment the count by 1.
this process happen until the condition true
and finally print the count.
