Instructions from your teacher:   Print multiplication tables for numbers from 1 to 10.   You should use for loop.   The output should look like this. (You have to print the whole tables). 1 x 1 = 1 1 x 2 = 2 . . . 1 x 10 = 10 --------------------------- 2 x 1 = 2 2 x 2 = 4 . . . 2 x 10 = 20 --------------------------- . . . --------------------------- . . . 10 x 9 = 90 10 x 10 = 100 -----------------------------     class Main { public static void main(String[] args) { } }

Coin Toss, v.2.0 Purpose. Learn how to use count-controlled loops. Requirements. Rewrite your coinTossl.cpp from exercise 6.5 as coinToss2.cpp. Modify the program to allow the user to specify (via keyboard data entry) the number of coin tosses to perform. When you run the program, and it should say the result of each coin toss (that is, "Heads" or "Tails"). Supplemental. Read about "randomizing" in www.rdb3.com/cpp/exercises/Gaming.supplemental.pdf. Algorithm. Call srand Prompt the user to enter how many coin tosses to perform Input and store the user's selection Create a counter and set it to zero Start the loop here If the counter equals the number of tosses to perform Break from the loop Get and store a randomly-generated number in the range 0 to 1 If the randomly-generated number equals 0 Output "heads" If the randomly-generated number equals 1 Output "tails" Add one to the counter Loop back from here Example. with user input in blue Enter the number of tosses to perform: 3 Heads…

More sophisticated computer-assisted instruction systems monitor the student’s perfor- mance over a period of time. The decision to begin a new topic is often based on the student’s success with previous topics. Write a program that will help an elementary-school student learn multiplication. Use Math.random to produce two positive one-digit integers. To count the number of correct and incorrect responses typed by the student. After the student answers 10 questions, your program should calculate the percentage of correct responses. If the percentage is lower than 75 percent, display Please ask your instructor for extra help, and reset the quiz so another student can try it.
