Answer:
A
Explanation:
B is a print statement.
C is a function invocation
D is a function declaration
A prototype is actually quite close to a declaration. The semi-colon at the end shows that no implementation will follow. Adding parameter names is allowed but would only be helpful for better understanding.
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.
