Answer:

The answer is: Only A is correct.

Explanation:

Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.

In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.

Hence, the answer is: Only A is correct.

Write a for loop that runs 5 times and accepts the input of an integer number every time. Those numbers will be accumulated by a
eduard

Answer:

import java.util.Scanner;

public class num2 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int total = 0;

       for(int i=0; i<5; i++){

           System.out.println("Enter next Int: ");

           total = total+in.nextInt();

       }

       System.out.println(total);

   }

}

Explanation:

In the code above written in Java programming language, the for loop statement for(int i=0; i<5; i++) ensures that the loop goes from 0-4 a total of five times.

At each iteration it requests a user to enter an int. The number entered is stored in the variable total which is initially assigned 0.

When the loop finishes execution, total is printed out

Ilya [14]

Answer:

Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/  etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.

Explanation:

  • As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:

  • Evaluate elements in parentheses.
  • Evaluate 'ranges' ().  
  • Evaluate 'intersections' (empty spaces).  
  • Evaluate 'unions' (,).
  • Perform negation (-).  
  • determine percentages (%).  
  • Perform exponentiation (^).  
  • Perform multiplication (*) and division (/), both are of equal precedence.  
  • Perform addition (+) and subtraction (-), both are of equal precedence.  
  • Evaluate text operators like (&).  
  • Perform comparisons like (=, <>, <=, >=).
