Solution:
/* C++ Program to Find Sum and Average of n numbers using for loop */
#include<iostream>
using namespace std;
int main()
{
int i,n,x,sum=0;
float avg;
cout<<"How many numbers u want to enter :: ";
cin>>n;
for(i=1;i<=n;++i)
{
cout<<"
Enter number "<<i<<" :: ";
cin>>x;
sum+=x;
}
avg=(float)sum/(float)n;
cout<<"
Sum of "<<n<<" Numbers :: "<<sum;
cout<<"
Average of "<<n<<" Numbers :: "<<avg;
cout<<"
";
return 0;
}
Output:
/* C++ Program to Find Sum and Average of n numbers using for loop */
How many numbers u want to enter :: 6
Enter number 1 :: 1
Enter number 2 :: 2
Enter number 3 :: 3
Enter number 4 :: 4
Enter number 5 :: 5
Enter number 6 :: 6
Sum of 6 Numbers :: 21
Average of 6 Numbers :: 3.5
Process returned 0

Assume an array of structure is in order by studentID field of the record, where student IDs go from 101 to 500. Write the most efficient pseudocode algorithm you can to find the record with a specific studentID if every single student ID from 101 to 500 is used and the array has 400 elements. Write the most efficient pseudocode algorithm you can to find a record with a studentID near the end of the IDs, say in the range from 450 to 500, if not every single student ID in the range of 101 to 500 is used and the array size is only 300
