HERE IS THE EXPLANATION FOR EACH LINE OF CODE

Arrays played crucial role in this code. Array is a data structure which stores fixed-size sequential collection of data.
To declare an array, we need specify the "type" of array and number of elements storing.
We can initialize array elements either one by one (as in this code) or as whole in '{}' seperated by commas.
Data inside array is accessed by index number which starts at 0 upto array size - 1.
After arrays, a for loop is used to iterate among the elements of array.
In for loop, updation of MatchesPlayed and TotalPoints are done through each iteration.
Also, calculation of Total played, won, loss, draw and points are done inside the for loop only.
Finally, printed the all values of arrays in a specific format to print as a table. Spaces are used to line up every value under each header.
See the pictures of editor and output, the way table was printed only with the spaces in output.

#include <iostream>

#include <string>

#include <iomanip>

#include<activaut.h>

#include<activdbg.h>

using namespace std;

int main()

{
// Declaration of arrays with array_size of 6(Number of teams).
int MatchesPlayed[6], MatchesWon[6], MatchesLost[6], MatchesDraw[6], MatchesPoints[6], TotalPoints[6];
// Initialization(assigning) of values for each team.

MatchesWon[0] = 3; MatchesLost[0] = 0; MatchesDraw[0] = 1; //India

MatchesWon[1] = 2; MatchesLost[1] = 0; MatchesDraw[1] = 1; //NZ

MatchesWon[2] = 0; MatchesLost[2] = 3; MatchesDraw[2] = 0; //Australia

MatchesWon[3] = 1; MatchesLost[3] = 2; MatchesDraw[3] = 1; //West Indies

MatchesWon[4] = 1; MatchesLost[4] = 0; MatchesDraw[4] = 1; //SA

MatchesWon[5] = 1; MatchesLost[5] = 3; MatchesDraw[5] = 0; //England
// Declaration and Initialization of totals.

int TotalPlayed = 0, TotalWon = 0, TotalLost = 0, TotalDraw = 0, TP = 0;

// for-loop to calculate the total matches played by each team and total points for each team.

for (int i = 0; i < 6; i++)

{

MatchesPlayed[i] = MatchesWon[i] + MatchesLost[i] + MatchesDraw[i]; //MATCHES FOR EACH TEAM

TotalPoints[i] = 2 * MatchesWon[i] - 1 * MatchesLost[i] + 1 * MatchesDraw[i]; //POINTS FOR TEAMS
// updating the totals for each match

TotalPlayed = TotalPlayed + MatchesPlayed[i];

TotalWon = TotalWon + MatchesWon[i];

TotalLost = TotalLost + MatchesLost[i];

TotalDraw = TotalDraw + MatchesDraw[i];

TP = TP + TotalPoints[i];

}
// format to print results as a table
