Chapter 2, Problem 14SA
Explanation of Solution
Expression to add byte variable and short variable:
The resultant data type after adding the “byte” variable and “short” variable is “int”. This is better illustrated with the help of a program.
// Class declaration
public class CheckPoint {
// Main function
public static void main(String[] args) {
// Declare the required variables
short a = 32767;
byte b = 127;
int c = a + b;
// Display the output
System.out.println(c);
}
}
In the above program,
- The variable “a” of data type “short” is declared...

- LISP Function help please LISP Programming only A function that generates a random day of the week, then displays a message saying that "Today is ... and tomorrow will be ...". Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt. Extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day. Make the function return true (t) instead of the last thing it evaluates, to avoid seeing the message printed more than once.arrow_forward(Physics) Coulomb’s Law states that the force, F, acting between two electrically charged spheres is given by this formula: F=kq1q2r2 q1isthechargeonthefirstsphere.q2isthechargeonthesecondsphere.risthedistancebetweenthecentersofthetwospheres.kisaproportionalityconstant.
