Explanation / Answer

#include<iostream.h>
#include<iomanip.h>
#include<conio.h>

float total_marks(float []);

main()
{
clrscr();

float marks[10][3]={0};

cout<<" Enter the marks of the ten students : "<<endl;

for(int count_1=0;count_1<10;count_1++)
{
cout<<" Enter the marks obtained by student "<<count_1+1<<
" :"<<endl;
cout<<" Question-1 = ";
cin>>marks[count_1][0];

cout<<" Question-2 = ";
cin>>marks[count_1][1];

cout<<" Question-3 = ";
cin>>marks[count_1][2];

  
}

getch();
clrscr();

cout<<" ********************************* Result Sheet *****************************"<<endl;
cout<<" Student No. Question-1 Question-2 Question-3 ";
cout<<"Total Marks "<<endl;

for(int count_2=0;count_2<10;count_2++)
{
cout<<setw(8)<<count_2+1;
cout<<setw(13)<<marks[count_2][0];
cout<<setw(11)<<marks[count_2][1];
cout<<setw(11)<<marks[count_2][2];
cout<<setw(11)<<total_marks(marks[count_2]);
cout<<endl;
}

cout<<" ******************************************************************************";

getch();
return 0;
}

/*************************************************************************///----------------------- total_marks(float []) -----------------------///*************************************************************************/float total_marks(float marks[])
{
float sum=0;

for(int count=0;count<3;count++)
sum+=marks[count];
