Which of these uses of type casting will NOT ensure that f is 1.5?

int a(1), b(2), c(2), d(2), e(2); double f; f = (a + b)*c / static_cast(d + e); // (ex1) f = static_cast(a + b)*c / (d + e); // (ex2) f = (a + b)*static_cast(c) / (d + e); // (ex3) f = static_cast((a + b)*(c) / (d + e)); // (ex4)

a. ex4
b. ex1
c. ex2
d. ex3

Write a method named addall that could be placed inside the hashintset class. this method accepts another hashintset as a parameter and adds all elements from that set into the current set, if they are not already present. for example, if a set s1 contains [1, 2, 3] and another set s2 contains [1, 7, 3, 9], the call of s1.addall(s2); would change s1 to store [1, 2, 3, 7, 9] in some order. you are allowed to call methods on your set and/or the other set. do not modify the set passed in. this method should run in o(n) time where n is the number of elements in the parameter set passed in.

Write a function named printfloatrepresentation(float number) that will print the floating point representation of a number using the format given below. (sign bit) exponent in binary (assumed bit).significandfor example if the number passed an argument is 71 yourprogram should print (0) 10000101 (1).00011100000000000000000similarl y if the number passed to the function as argument is -71 the program should print (1) 10000101 (1).00011100000000000000000
