C++ Programming: Arrays and Functions

Include Statements and Namespaces

• The code begins with #include <iostream> and #include <cstring>, indicating the use of input/output operations and character string manipulation.
• using namespace std; brings standard library components into the current scope, simplifying code.

Constants and Data Structures

• const int NB_TEAMS = 5; defines the number of teams as a constant.
• const int SIZE = NB_TEAMS + 1; calculates a size value likely related to an array dimension for the score board.
• int SB[SIZE][SIZE]; declares a 2D array named SB to store the score board information, likely team vs. team scoring.
• int WS[SIZE][5]; declares a 2D array named WS to store weekly standings data, with likely attributes like team ID, points, goals scored (GS), goals against (GA), etc.

Function Prototypes

• A series of function prototypes define functions that manipulate SB and WS data, including initializing these arrays.

Main Function

• int main(): The entry point of the program.
• initializeBoard(SB); initializes the score board (SB) to -1, preparing for data input.
• initializeWeeklyStanding(WS); initializes the weekly standings (WS) data.
• A while loop iterates until the championship is over based on a condition checked by isChampionshipOver().
• enterResults(SB, WS); takes results from user input for matches.
• showWeeklyLeagueStanding(WS); displays the current weekly league standings.
• return 0; indicates successful program execution.

Initialization Functions

• initializeBoard(int SB[][SIZE]): Initializes the score board array SB to -1. This implies that the data is initially empty.
• initializeWeeklyStanding(int WS[][5]): Initializes the WS array with team IDs (column 1) and initializes other attributes to zero.

Data Entry and Display Functions

• enterResults(int SB[][SIZE], int WS[][5]): This is central to user input, prompting for home and away team goals.
  • It validates user input for team numbers and ensures teams haven't already played.
  • It calculates changes in weekly standing based on the entered results.
• showWeeklyLeagueStanding(int WS[][5]): Displays the current standings based on calculated points for each team.

Condition Check Function

• isChampionshipOver(const int SB[][SIZE]): Checks if the championship is over, likely by verifying if all possible match results are available.

Sorting Function

• sortWeeklyLeagueStandingByPoints(int WS[][5]): Sorts the data in the WS array based on descending weekly points, likely for the team standings display.
