An array stores details of 25 students (rollno, name, marks in three subject):

#include<iostream.h>

#include<conio.h>

struct stud

{

int roll;

char nm[50];

float m1, m2, m3;

};

typedef stud S;

void main()

{

S student[25];

for(int i =0 ; i < 25 ; i++)

{

cout << "\n Enter Roll no :  ";

cin >> student[i].roll;

cout << "\n Enter Name : "

cin.getline(student[i].nm, 50);

cout << "\n Enter marks of three subjects :";

cin >> student[i].m1 >> student[i].m2 >> student[i].m3 ;

}

cout<< "\n STUDENTS FAILED IN MORE THAN 1 SUBJECT \n ";

for(i =0 ; i < 25 ; i++)

{

if(( student[i].m1< 40 && student[i].m2 < 40) || (student[i].m2 < 40 && student[i].m3 < 40) || ( student[i].m1 < 40 && student[i].m3 < 40))

cout << student[i].roll  << "\t" << student[i].nm << "\n";

}

getch();
