Write a function which takes one parameter int num, and prints out a countdown timer with minutes and seconds separated by a colon (:). It should print out one line for each elapsed and then pause one second before printing out the next line. After it has done all of this, it should call a special function ringAlarm () to sound an alarm. A few things - You can assume that calling the function sleepytime () makes the program pause for one second - You can assume that calling the function ringAlarm () makes the program sound an alarm - It should count down from num minutes:zero seconds to zero minutes:zero seconds - Your function must have the following signature: void timer (int num) You do not need to demonstrate calling this function from main(). You don't need to format the output nicely; the below is acceptable output for calling this function when num is 10: 10:0 9:59 9:58 //..and so on, all the way down to: 9:1 9:0 8:59 8:58 //..and so on, all the way down to: 0:2 0:1 0:0

Write a program that simulates coin tossing. For each toss of the coin the program should print Heads or Tails. Let the program toss the coin 100 times and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip that takes no arguments and return 0 for tails and 1 for heads. flip depends on the rand function to simulate coin toss [Note: if the program realistically simulates the coin tossing, then each side of the coin should appear approximately half the time for a total of approximately 50 heads and 50 tails].
