The program illustrates the use of arrays and loops.
Arrays are data types that hold multiple values in a variable, while loops are used to perform repetitive operations
The program in C++, where comments are used to explain each line is as followed:
#include <iostream>
using namespace std;
int main(){
//This declares a 2D array of 10 rows and 5 columns
int scores [10][5];
//The following iteration gets input into the 2D array
for(int i = 0; i < 10;i++){
for(int j = 0; j <5; j++){
cin>>scores[i][j];
}
}
//This declares an array for the average score by each student
int average [10];
//This initializes a counter k to 0
int k = 0;
//This iterates through the scores of each student
for(int i = 0; i < 10;i++){
//This prints an output header
cout<<"Student "<<i+1<<": ";
//This initializes the student score to 0
int score =0;
for(int j = 0; j <5; j++){
//This prints the current score of the student
cout<<scores[i][j]<<" ";
//This calculates the total score
score+=scores[i][j];
}
//This calculates the average score
average[k] = score/10;
k++;
//This prints a new line
cout<<'\n';
}
//This declares an array for the average score in each subject
int marks [5];
//This initializes a counter k to 0
k = 0;
//This iterates through the scores of each subject
for(int i = 0; i < 5;i++){
int score =0;
for(int j = 0; j <10; j++){
//This calculates the total score
score+=scores[j][i];
}
//This calculates the average score
marks[k] = score/10;
k++;
}
return 0;
}
