Answer:
#include <iostream>
using namespace std;
int main() {
int *ip_arr,n;//pointer name inp_arr and integer n to store the size.
cin>>n;//size.
for(int i=0;i<n;i++)
ip_arr[i]=-1;//assigning -1 to every element.
for(int i=0;i<n;i++)
{
cout<<ip_arr[i]<<" ";//printing every element.
}
return 0;
}
output:-
100
-1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
Explanation:
I am taking input of size.You should enter 100 for 100 values which have value -1.
Since Bilmain manufactures has recruited you as a network administrator to handle the organization's network operations, the subnet mask for this class A address is 255.0.0.0.
<h3>Why is a subnet mask of 255 usually used?</h3>
The 255 address, or host address of all ones in binary notation, is used to send a message to every host on a network. It's important to keep in mind that no host can be given the first or final address in a network or subnet. You ought to be able to assign IP addresses to 254 hosts at this point.
A subnet mask is a 32-bit integer that is produced by setting all host bits to 0 and all network bits to 1. The subnet mask does this by dividing the IP address into network and host addresses. The "0" address is always a network address, but the "255" address is always allocated to a broadcast address.
Hence, The subnet mask for a class C network would be 255.255.255.0, which indicates that 24 bits are being used for the network. This is shown in CIDR notation by adding a /24 after the IP address.
