Answer: must have public properties that match the names of the bound fields
Explanation:
When a business class is used with an object data source, the business class must have public properties that match the names of the bound fields.
Having an attribute which match the names of the bound fields isn't necessary as well as having a constructor with parameters that match the names of the bound fields
Therefore, the correct option is B.
I don't know but I am guessing 666 or 777 or 888.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int n;
double average,sum=0,x;
cout<<"enter the Value of N:";
// read the value of N
cin>>n;
cout<<"enter "<<n<<" Numbers:";
// read n Numbers
for(int a=0;a<n;a++)
{
cin>>x;
// calculate total sum of all numbers
sum=sum+x;
}
// calculate average
average=sum/n;
// print average
cout<<"average of "<<n<<" Numbers is: "<<average<<endl;
return 0;
}
Explanation:
Read the total number from user i.e "n".Then read "n" numbers from user with for loop and sum them all.Find there average by dividing the sum with n.And print the average.
Output:
enter the Value of N:5
enter 5 Numbers:20.5 19.7 21.3 18.6 22.1
average of 5 Numbers is: 20.44
4 because it’s a triangular ruler
