Explanation / Answer

int main()

{

//create three student records

STUDENT_TYPE student[3];

int best_student, i;

double best_GPA;

for(i=0;i<3;i++)

{

cout<<"Enter details for the student#"<<i+1<<endl;

cout<<"Name:";

cin>>student[i].name;

cout<<"ID : ";

cin>>student[i].ID;

cout<<"GPA :";

cin>> student[i]. GPA;

cout<<"Major: ";

cin>>student[i].Major;

cout<<"_____________________________________________________________"<<endl;

}

//best student

best_GPA=-1.0;

best_student=-1;

for( i=0;i<3;i++)

{

if(student[i].GPA>best_GPA)

{

best_GPA=student[i].GPA;

best_student=i;

}

}

if (best_student!=-1)

cout<<"Best student is "<< student[best_student].name<<"with GPA= "<<best_GPA<< endl;

else

cout<<"Highest GPA isnot distinct.No single best student could be found."<<endl;

//student with ID 101

for( i=0;i<3;i++ )

{

if (student[i].ID==101)

{

cout<<"Student"<<student[i].name<<"has ID 101."<<endl;

}

}

return 0 ;

}
