This is called a key attribute!
There are different types of key attributes!
Primary key is the key that is actually chosen, for example a social security number.
There is also a unique key, say our finger prints! they also uniquely identify humans, but usually we prefer to use social security number when we list people (a unique key could be a primary key if we chose so)
We could also identify people by their social security number and a name, but this is unnecessary, as social security number already gives a full identification. Such a reduntant key is called super key.
In python:
i = 1
lst1 = ([])
lst2 = ([])
while i <= 5:
person1 = int(input("Enter the salary individual 1 got in year {}".format(i)))
person2 = int(input("Enter the salary individual 1 got in year {}".format(i)))
lst1.append(person1)
lst2.append(person2)
i += 1
if sum(lst1) > sum(lst2):
print("Individual 1 has the highest salary")
else:
print("Individual 2 has the highest salary")
This works correctly if the two individuals do not end up with the same salary overall.
Answer:
// here is code in c++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main() {
// variable
int num;
int tot_sum=0;
cout<<"enter a number: ";
// read the value of n
cin>>num;
// check the multiple of 2 or 5 from 1 to n
for(int x=1;x<=num;x++)
{
// if multiple of 2 or 5 then add them
if(x%2==0 ||x%5==0)
{
tot_sum=tot_sum+x;
}
}
// print the sum
cout<<"sum of multiple of 2 or 5 is:"<<tot_sum<<endl;
return 0;
}
Explanation:
Read the number "n" from user.Check every number from 1 to n, if it is a multiple of 2 or 5 then add them to "tot_sum".When the for loop end, "tot_sum" will have sum of all the number which are either multiple of 2 or 5.Print the sum.
Output:
enter a number:11
sum of multiple of 2 or 5 is:35
The answer would be Mesozoic.
HOPE THIS HELPS YOU! ^_^
