You have an upcoming exam and you are confident that you have read all your books and believe you know your stuff down cold. Somehow, after sitting for your exam, you fail. To avoid this from happening again, you can use methods like SQRW or KWL to make sure that you get a better grade. Each of these techniques are initials that stand for “Survey”, “Question”, “Read”, and “Write” (SQRW) and “Know,” “Want to Know,” and “Learned” (KWL) respectively. People who make the most out of these two strategies will understand what they read and prepare notes of what they learned. These notes will come in handy when sitting for an exam. KWL, specifically, help student become better versions of themselves and improve in reading expository text.
 
        
             
        
        
        
Following are the program to calculate even digits sum:
<h3>Program:</h3>
#include <iostream>//header file
using namespace std;
int main()//main method
{
    int a[10],s=0,i;//defining an array and an integer variable
    cout<<"Enter array values: ";//print message
    for(i=0;i<=9;i++)//defining a loop that input array value
    {
        cin>>a[i];//input array value
    }
    for(int i=0;i<=9;i++)//defining loop that check array value 
    {
        if(a[i]%2==0)//defining if block that checks even number condition value
        {
            s=s+a[i];//adding even number value
        }
    }
    cout<<"The sum of even number is: "<<s;//print even number sum value
    return 0;
}
Program Explanation:
- Defining a header file.
- Defining the main method.
- Inside the main method, an integer array "a", and two integer variable "s,i" is declared.
- In the next step, a for loop is declared that input the array value, and after input value another loop is declared that check even number value in array.
- In this loop it adds array value and after adding the value a print method is declared that prints its value.
Output:

Explanation:
The advantages of java.util.Stack are as following:-
- java.util.Stack is an implementation of the vector class hence it can keep track of position of elements in the stack hence it is not required to store an additional pointer for each node.
- In the implementation it allocates space only that much is needed.
These are the two advantages of java.util.Stack.
