- 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…arrow_forwardTake a four-digit number. Add the first two digits to the last two digits. Now, square the sum. Surprise, you have got the original number again. Of course, not all four-digit numbers have this property. Write a C program to find three numbers that have this special property and display those numbers on 7-segment LEDS for at least 2 seconds. *USE C PROGRAMNG FOR MICROPROCESSOR*arrow_forwardJava Task 1. Implement a for loop to compute the sum of 1+2+3+…+n. The ending number n is entered by a user. Print out the sum. Test your program with the following cases. When input n is 3, the sum is 6; when input n is 4, the sum is 10. 2. Write an equivalent while loop to solve the same problem.arrow_forward
