/* Homework Lab 37

In this program the user will enter the following information for historical baseball players (up to the maximum number of players indicated by MAX_NUM_OF_PLAYERS):

The player's name The number of hits they got in their career The number of at bats during their career

The information that the user enters must be stored in parallel arrays (one array for each statistic listed above). When the user says they are done entering players -OR- they have entered the maximum number of players, then a chart must be produced on the screen showing each player's name and their batting average. Batting average is calculated as follows (and will be calculated with a function you prototype, implement, and call):

batting average = # of hits # of at bats

Note: Don't forget that hits and at bats will be stored in arrays

In addition to displaying the batting average chart, the program also needs to determine which player has the highest batting average and display the name of the batting champion.

To complete this assignment, follow the TODO steps listed below. */

// TODO - Step 1a // Declare function prototype // Name: BattingAverage // Parameters: an int for the number of hits // an int for the number of at bats // Returns: a float for the calculated batting average (hits at bats) // // After completing this step, jump past main() to do Step 1b, then come back to continue with Step 2

int main() { const int MAX_NUM_OF_PLAYERS = 10;

/* TODO - Step 2 Declare 4 arrays, with the data types listed below - each holding as many values as determined by the constant declared above:

- array of string, to hold the names of the players - array of int, to hold the hits for each player - array of int, to hold the number of at bats for each player - array of float, to hold the calculated batting average for each player */

// Parallel array declarations

// These variables will hold array index values int currentPlayerIndex = 0; // used when user enters data, to retain current array index int battingChampIndex = 0; // array index that points to the player with the highest average

// Loop control variable, holds 'y' if player wants to add another player char again;

/* TODO - Step 3 Complete the DO...WHILE loop that has been started here. You will need to scroll down (after STEP 11) to where the following line is commented out:

//} while (expression);

Uncomment the line and change "expression" so the loop repeats if: - the user indicated they want to add another player, AND - fewer than MAX_PLAYERS have been added */

/* TODO - Step 8 - Prompt the user for the number of at bats for this player - Read the user's answer and store to the correct array in the correct location */

/* TODO - Step 9 Write a WHILE loop to validate the user's entry. If the user's entry for at bats less than the number of hits: - Display an error message (example in 3rd player Sample Output below) - Read the user's answer again and store to the correct array in the same location */

/* TODO - Step 10 Increment the index that is being used for the parallel arrays, readying it for the next time around loop */

/* TODO - Step 11 If the parallel array index is still less than the max number of players allowed (as identified by the MAX_NUM_OF_PLAYERS constant), then - display a prompt to ask the user if they want to enter another player - read the user's answer from the keyboard (into the 'again' variable declared above) - convert the user's answer to lower case and store it back to the same 'again' variable
