}

}

//function to show all the grade

function showAlltheGrades()

{

for(i=0;i<10;i++) //using for loop to display details

{

grade[i].detail();//call method on the object

}

}

//function to display MaxGrade

function MaxGrade()

{

//considering first element grade as max grade

var mgrade=grade[0].grade;

var names="";//variable to get name

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

{

if(mgrade<grade[i].grade)//checking grade

{

mgrade=grade[i].grade;//get grade

names=grade[i].name;//get name

}

}

//print max grade and name

document.write("Max Grade:"+mgrade+" Name:"+names);

}

inputGrade();//call function to get input

showAlltheGrades();//call function to display names

MaxGrade();//call function to find max grade
