- Which of the following best describes the value of the Boolean expression: a && !(b || a) The value is always true. The value is always false. The value is true when a has the value false, and is false otherwise. The value is true when b has the value false, and is false otherwise. The value is true when either a or b has the value true, and is false otherwise.“As one variable goes up, the other variable goes down” is a description of:Let s1 be " Welcome " and s2 be " welcome ". Write the code for the following statements:a. Check whether s1 is equal to s2 and assign the result to a Boolean variable isEqual.b. Check whether s1 is equal to s2, ignoring case, and assign the result to a Boolean variable isEqual.c. Compare s1 with s2 and assign the result to an int variable x.d. Compare s1 with s2, ignoring case, and assign the result to an int variable x.e. Check whether s1 has the prefix AAA and assign the result to a Boolean variable b.f. Check whether s1 has the suffix AAA and assign the result to a Boolean variable b.g. Assign the length of s1 to an int variable x.h. Assign the first character of s1 to a char variable x.i.

- In admissions to military high schools, the age of the candidate should be between 13 - 17 (including lower and upper limit) and body mass index should be in the range of 18.50 - 24.99 (including lower and upper limit). (Body mass index is calculated by dividing weight by the square of height in meters. BMI = weight / height2). Write the JAVa program on the screen that will show whether the candidate will be admitted to military high school according to age, weight and height information entered on the keyboard.4. Step through each line of the JavaScript program below. (This is the program from Figure 17.1.) Write down the value of each variable as you walk through it. Use an order of a 16 oz. latte with 2 shot. var price; var taxRate = 0.088; if (drink == "espresso") price = 1.40; if (drink == "latte" || drink == "cappuccino") { if (ounce == 8) price = 1.95; if (ounce == 12) price = 2.35; if (ounce == 16) price = 2.75; } if (drink == "Americano") price = 1.20 + .30 * (ounce/8); price = price + (shots - 1) * .50; price = price + price * taxRateCode a JavaScript function called isLeapYear() that accepts one integer value as its parameter and will return true if this value is a leap year and false if it is not. 19.Rules: A leap year is divisible by four but not divisible by 100 unless it is divisible by 400. E.g. 1600, 1912, 1996, 2000, 2020 and 2124 are leap years where 1000 and 3000 are not.
