Questions: 1. Write a recursive function string Reverse that takes a character array as an argument, prints it back to front and retums nothing. The function should stop processing and return when the terminating null character of the string is encountered Example output: Print this string backward. .drawkcab gnirts siht tnir Press any key to continue... 2. Write a recursive function power buse, exponent) that when invoked retums base exponent For example, power( 3.4) - 3*3*3*3. Assume that exponent is an integer greater than or equal to 1. Hint: The recursion step would use the relationship basexponunt = base. base exponent-1 and the terminating condition occurs when exponent is equal to 1 because basel = base 3. 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 returns 0 for tails and 1 for heads. [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.] 4. Write a program that displays the multiplication table for numbers 0 to 9. Example Multiplication table 1 to 10 is given below B 1 1 2 3 --- 2 3 4 Time Table - 10x15 2 3 5 6 7 9 10 2 3 5 5 10 8 10 12 14 16 20 6 9 15 19 25 24 27 30 12 16 20 24 28 32 36 10 35 20 25 1014 45 1210 24 30 36 4243 54 14 21 20 49 55 20 16 32 56 54 10 36 45 720190 20 30 40 50 60 70 30 100 5 5 6 7 SSRS 7 9 - 10 10
