1: Import the Standard Input Output library
3,4,5,6: Define four macros:
    a. MAX_JUDGES
    b. MAX_STRING
    c. MAX_CONTESTANTS
    d. WINNER_CUTOFF
8. Declare a struct called "Score" with the following datatypes:
    a. "judgeScore": an array of doubles with a maximum capacity of 3
13. Declare a struct called "Contestant" with the following datatypes:
    a. "name": an array of characters with a maximum capacity of 25
    b. "score": an instance of the struct "Score"
    c. "average": a double
20. Declare a struct called "Competition" with the following datatypes:
    a. "compName": an array of characters with a maximum capacity of 25
    b. "contestants": an array of instances of the struct "Contestant" with a maximum length of 10
    c. "numContestants": an integer
27. Declare a function called "avg" with the return type of "double" and which accepts a constant pointer argument of type "Contestant"
29. Function definition for "avg".
    Returns the value of the following expression:
    (c->score.judgeScore[0] + c->score.judgeScore[1] + c->score.judgeScore[2]) / 3.0;
    Where "c" is the argument passed into the function
32. "main" function begins
34. Declare an array of instances of the type "Contestant" called "winners" with a maximum capacity of 10, and initialize it with one item with the value of 0
35. Declare an instance of the type "Competition" called "national" and initialize it with the following data:
{ "National", { { "Jill Smith", { 8, 8, 7 } }, { "Ellen Jones", { 8.5, 5.5, 8 } }, { "Joan Bell", { 9.5, 3.5, 6 } } } }
45. Declare four integer variables: "i", "j", "k" and "numWinners" and initialize them with 0
47. FOR LOOP
    CONDITION: i < national.numContestants 
               0 < 3 (TRUE. Execute for loop body:)
      49. Call "avg" with the following argument:
            &national.contestants[i]
            &({"Jill Smith", {8, 8, 7}})
          Assign result to national.contestants[i].average
            national.contestants[0].average = 7.666666666666667
      50. Check if the following expression is TRUE:
            national.contestants[0].average >= WINNER_CUTOFF
            7.666666666666667 >= 6.5 (TRUE: Execute IF block)
      52. FOR LOOP
          CONDITION: j < numWinners && winners[j].average < national.contestants[i].average
                     0 < 0 && 0 < 7.666666666666667 (FALSE: Skip the loop)
      56. FOR LOOP
          CONDITION: k > j
                     1 > 0 (TRUE: Execute IF block)
      60. assign value of national.contestants[i] to winners[j]
                        -> winners[0] = {"Jill Smith", {8, 8, 7}, 7.666666666666667}
      61. Increment the value of "numWinners" by 1: numWinners = 1
47. FOR LOOP
    CONDITION: i < national.numContestants 
               1 < 3 (TRUE: Execute for loop body) 
      49. Call "avg" with the following argument:
            &national.contestants[i]
            &({"Ellen Jones", {8.5, 5.5, 8}})
          Assign result to national.contestants[i].average
            national.contestants[1].average = 7.333333333333333
      50. Check if the following expression is TRUE:

                     0 < 0 && 0 < 7.333333333333333 (FALSE: Skip the loop)
      56. FOR LOOP
          CONDITION: k > j
                     1 > 0 (TRUE: Enter the loop)
          57. Assign the value of winners[k - 1] to winners[k]
                                ->winners[1] = {"Jill Smith", {8, 8, 7}, 7.666666666666667}
      60. assign value of national.contestants[i] to winners[j]
                        -> {"Ellen Jones", { 8.5, 5.5, 8 }, 7.333333333333333}
      61. Increment the value of "numWinners" by 1: numWinners = 2
47. FOR LOOP
    CONDITION: i < national.numContestants 
               2 < 3 (TRUE: Execute for loop body) 
    TRUE. Execute for loop body:
      49. Call "avg" with the following argument:
            &national.contestants[i]
            &({"Joan Bell", {9.5, 3.5, 6}})

            6.333333333333333 >= 6.5 (FALSE: Skip IF block)
64. Call the printf function.
    OUTPUT: "Winners of the national competition\n"
65. FOR LOOP
    CONDITION: i < numWinners
               0 < 2 (TRUE: Enter the loop)
