Use two dimensional array to store marks of student for each subject.

 source file name: arr2davg.C

#include<stdio.h>

int  main()

{

int i,j,sum=0,avg;

int stud[10][5]={

{501,15,15,15,15},{502,16,16,16,16},{503,15,16,17,20},

{504,17,18,19,20},{505,11,12,13,14},{506,12,14,16,18},

{507,17,15,19,14},{508,11,14,17,19},{509,12,16,14,18},

{510,13,14,15,16}};

//clrscr();

printf("\n Student Roll no and Average marks list: ");

for(i=0;i<10;i++)

{

sum=0;

for(j=1;j<5;j++)

{

sum=sum+stud[i][j];

}

avg=sum/4;

printf("\n  %d  %d ",stud[i][0],avg);

}

//getch();

return 0;

}
