Question

JAVASCRIPT:

- Please create an object (grade) with 10 names and 10 grades.
- Create a method (inputGrade) that can put a name and a grade to the grade object.
- Create another method (showAlltheGrades) to show all the grade in that object.
- Create the third method (MaxGrade) that can display the maximum grade and the student name.
- Using “prompt” and inputGrade method input 10 student names and their grades.
- Display all the grades and names by using showAlltheGrades method.

NOTE: Make sure to use the push() method when adding elements to the arrays.

Please post the code and a screenshot of the output. Thanks!

Answer 1

I've declared the names initially as well as I have given them using the inputGrade method. Choose the one you are required.

Code:

var grade = {
   name: ["Name1","Name2","Name3","Name4","Name5","Name6","Name7","Name8","Name9","Name10"],
   score: ["44","83","74","54","65","66","44","76","56","71"],
   inputGrade: function(data1,data2){
       grade.name.push(data1);
       grade.score.push(data2);
   },
   showAlltheGrades: function(){
       for ( var i=0; i<grade.name.length; i++ ) {
           console.log(grade.name[i]+":"+grade.score[i]);
       }
   },
   MaxGrade: function(){

       var max = grade.score[0];
       var index = 0;

       for (var i = 1; i < grade.score.length; i++) {
           if (grade.score[i] > max) {
               index = i;
               max = grade.score[i];
           }
       }

       console.log("Maximum Grade: "+grade.name[index]+" , "+grade.score[index]);
   }
};

var name,score;
for (i = 0; i < 10; i++) {
   name=prompt("Please enter Student "+i+" Name : ");
   score=prompt("Please enter Student "+i+" Grade : ");
   grade.inputGrade(name,parseInt(score));
}

Output:
