clrscr();

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

{

printf("\nEnter marks of students %d in 3 subjects:",i+1);

scanf("%f%f%f",&s1[i],&s2[i],&s3[i]);

}

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

{

sum[i]=s1[i]+s2[i]+s3[i];

avg[i]=sum[i]/3;

}

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

printf("\nStudent %d's marks:\nTotal : %.2f\nAverage : %.2f",i+1,sum[i],avg[i]);

getch();
