<span>A selective backup allows a user to choose specific files to back up, regardless of whether or not the files have been changed.</span>
I believe the answer is B. Optimization because it means to make work more efficient but I might be wrong. Checking definitions, this one seems more logical.
Answer:
an error message
Explanation:
The return value is the value which is sent back by the function to a place in the code from where the 
was called from. Its main work is to return a value form the function.
In the context, the form of "(symbol-length? 'James)" in Scheme will return the value --- ' an error message'.
Answer:
#include <bits/stdc++.h>
using namespace std;
int main() {
int A[3][3],B[3][3],res[3][3],i,j;
srand(time(0));//for seed.
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
int val=rand()%100+1;//generating random values in range 1 to 100.
int val2=rand()%100+1;
A[i][j]=val;
B[i][j]=val2;
}
cout<<endl;
}
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
res[i][j]=0.5*A[i][j]+3*B[i][j];//storing the result in matrix res.
}
}
cout<<"Matrix A is"<<endl;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<A[i][j]<<" ";//printing matrix A..
}
cout<<endl;
}
cout<<"Matrix B is"<<endl;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<B[i][j]<<" ";//printing matrix B..
}
cout<<endl;
}
cout<<"The result is"<<endl;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<res[i][j]<<" ";//printing the result..
}
cout<<endl;
}
return 0;
}
Output:-
Matrix A is
13 95 83
88 7 14
24 22 100
Matrix B is
11 13 95
48 35 20
68 100 18
The result is
39.5 86.5 326.5
188 108.5 67
216 311 104
Explanation:
I have created 2 matrices A and B and storing random numbers int the matrices A and B.Then after that storing the result in res matrix of type double to store decimal values also.Then printing the res matrix.
Deep Learning enables image processing, speech recognition, and complex game play in artificial intelligence.
<h3>What is Deep learning?</h3>
This is known to be a part of machine learning, and it is seen as neural network that is made up of three or more layers which tries to simulate the behavior of the human brain.
Note that Deep Learning enables image processing, speech recognition, and complex game play in artificial intelligence.
