Answer:
Explanation:
When you have a single copy, a large number of concurrent updates that are supposed to go to a file may result in the user obtaining incorrect information. This incorrect information obtained them leads to the file being left in an incorrect state. When you have a lot of or multiple copies, then storage waste exist and the various copies might happen not to be consistent with respect one other. In summary, what happens is that
a) Using one copy saves space, but also the change might have an effect on all the users.
b) Using multiple copies avoids eliminates the change problem, while creating its own problems, using more space.
Its outdated maybe because of time issues or over-usage<span />
D) both a and b
Microwaves are used to heat foods in ovens. We all know that. They are also used for data and information transfer. Microwaves are used in wifi, gps, and radio astronomy.
Answer:
// here is code in c++.
#include <bits/stdc++.h>
using namespace std;
int main()
{
// variable to read row and column of 2-d array
int r,c;
cout<<"enter the number of row:";
// read number of row
cin>>r;
cout<<"enter the number of column:";
// read number of column
cin>>c;
// create an array of size rxc
int arr[r][c];
cout<<"enter the elements of the array:"<<endl;
// read the elements of 2-d array
for(int i=0;i<r;i++)
{
for(int j=0;j<c;j++)
{
cin>>arr[i][j];
}
}
cout<<"numbers which are greater than 10 in 2-d array"<<endl;
for(int i=0;i<r;i++)
{
for(int j=0;j<c;j++)
{
// if element is greater than 10, print it
if(arr[i][j]>10)
cout<<arr[i][j]<<" ";
}
cout<<endl;
}
return 0;
}
Explanation:
Read the size of 2-d array i.e row and column.Create a 2-d array of size rxc of integer type.Read the elements of the array. Then traverse the array and if an element if greater than 10 then print that element.
Output:
enter the number of row:3
enter the number of column:3
enter the elements of the array:
23 45 53 78 1 9 6 8 77
numbers which are greater than 10 in 2-d array
23 45 53
78
77
