18th Week OJ Test Project 3--array score statistics

define a 5Line3A two-dimensional array of columns, each representing a student's high number, English,C + +Achievements. And then define a 5one-dimensional array of elements that are used to store each student'saverage score. Please enter the student's course scores, output a transcript with an average score, and an average of all student averages.

The code is as follows:

#include <iostream> #include <iomanip>using namespace Std;int main () {    int score[5][3];    Double average[5];    int i,j;    Double sum=0;    for (i=0; i<5; i++) for        (j=0; j<3; j + +)            cin>>score[i][j];    for (i=0; i<5; i++)        average[i]=0;    For (i=0, i<5; i++)    {for       (j=0; j<3; j + +)            average[i]+=score[i][j];        average[i]=average[i]/3.0;        Sum+=average[i];    }    For (i=0, i<5; i++)    {for        (j=0; j<3; j + +)            cout<<score[i][j]<< "";        Cout<<setiosflags (ios::fixed) <<setprecision (2) <<average[i]<<endl;    }    Cout<<setiosflags (ios::fixed) <<setprecision (2) <<sum/i<<endl;    return 0;}
