Write a user input program using if else statements ONLY name of program "Magic number" the user will try guess the Magic number. The user will enters the number to guess and computer will tell the user if the number matches the Magic number and then determine if the number is smaller or greater than the initial number. The Number that is guessed must be of type int and use Math. random() function to give it random value in range 1 thru 100.

3.12: the speed of sound the speed of sound depends on the material the sound is passing through. below is the approximate speed of sound (in feet per second) for air, water and steel: air: 1,100 feet per second water: 4,900 feet per second steel: 16,400 feet per second write a program class the speed of sound that asks the user to enter “air”, “water”, or “steel”, and the distance that a sound wave will travel in the medium. the program should then display the amount of time it will take. you can calculate the amount of time it takes sound to travel in air with the following formula: time = distance/1,100 you can calculate the amount of time it takes sound to travel in water with the following formula: time = distance/4,900 you can calculate the amount of time it takes sound to travel in steel with the following formula: time = distance/16,400
