The Avengers League array score statistics

Description

Defines a two-dimensional array of 5 rows and 3 columns, each representing a student's high number, English, and C + + scores. Define a one-dimensional array with 5 elements to store the average score for each student. Please enter the student's course scores, output a transcript with an average score, and an average of all student averages.

Input

15 integers representing 5 students in 3 subjects

Output

Show each student's grade and average score in 5 lines
Show average values for all students (keep two decimal places)

Sample Input

97 78 8778 63 6873 81 8591 87 8876 81 89

Sample Output

97 78 87 87.3378 63 68 69.6773 81 85 79.6791 87 88 88.6776 81 89 82.0081.47

HINT

Can be completed on the basis of the following program framework, additional variables required in the calculation are added by themselves

#include <iostream>

#include <iomanip>

using namespace Std;

int main ()

{

int score[5][3]; An array of saved scores

Double average[5]; An array that holds average scores

int i,j;

Enter your score

for (i=0; i<5; i++)

for (j=0; j<3; j + +)

cin>>score[i][j];

Calculates the average score for each student, saved to the array average

Output transcripts with an average score

Averages the average score and outputs

return 0;

}

Solution:

#include <iostream> #include <iomanip>using namespace Std;int main () {double d;double score[5][3];d ouble Average[5];int i,j;for (i=0; i<5; i++) for (j=0; j<3; j + +) cin>>score[i][j];average[0]= (score[0][0]+score[0 ][1]+SCORE[0][2])/3;average[1]= (score[1][0]+score[1][1]+score[1][2])/3;average[2]= (score[2][0]+score[2][1]+ SCORE[2][2])/3;average[3]= (score[3][0]+score[3][1]+score[3][2])/3;average[4]= (Score[4][0]+score[4][1]+score[4] [2]) /3;d= (Average[0]+average[1]+average[2]+average[3]+average[4])/5;for (i=0;i<=4;i++) {for    (j=0;j<=2;j++)    {        cout<<setiosflags (ios::fixed) <<setprecision (0) <<score[i][j];        cout<< "";    }    Cout<<setiosflags (ios::fixed) <<setprecision (2) <<average[i]<<endl;} Cout<<d;return 0;}
