Design a program that gives simple math quizzes. the program should display two random numbers that are to be added, such as: 247 129. the program (java language) should allow the student to enter the answer. if the answer is correct, a message of congratulations should be displayed. if the answer is incorrect, a message showing the correct answer should be displayed. here is the pseudo-code to follow
//declare the variables to hold intermediate and final values
declare integer rand1, rand2, sum ans
//get the random numbers generated by the function
//random and assign those values in rand1 and rand2 respectively
set rand1 = random(1, 999)
set rand2 = random(1, 999)
//dsiplay rand1 and rand2 in a formatted way treated for addition
display

Write a program that prompts the user to input a string. the program then uses the function substr to remove all the vowels from the string. for example, if str = "there", then after removing all the vowels, str = "thr". after removing all the vowels, output the string. your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
