Question

4. Design a for loop that would add all the odd numbers starting from 1 to 1001 and store in the variable sum (10 points) 5. [Programming Exercise) (20 POINTS) Write a Program that will use a function named Grade which will take three inputs: homeworks, midterm and final and compute average using 20% of homeworks, 30% from midterm and 50% from final. Then it will compute the letter Grade by using the following: If the average is greater or equal to 90, then grade is A, if> 80, but less than 90 grade is B. if >=70 but less than 80, grade is C, any other score grade is F From main, call this function by providing the inputs. Display the average and grade from main.

Answer 1

4) For this question we would write a For loop that would start with 1 and it would run till 1001 and we will check if number is odd.

int sum=0;

for (int i=1;i <= 1001;i++){

if(i%2 !=0){

sum=sum+i;

}

}

5) Here I am writing this code using Java language. In this code we will write a Method called Grade that would be called from main.

Class Score{

public int average {get;set;}

public string grade{get;set;}

public Score(int average,string grade){

this.average=average;

this.grade=grade;

}

public static void main(String[] args){

Score sc=Score(30,50,70);

System.out.println("Average is : "+sc.average + " grade is : " +sc.grade);

}

public static Score Grade(int homeworks , int midterm , int final){

int total = (homeworks*20/100)+(midterm*30/100)+(final*50/100);

int average=total/3 ;

string grade="";

if(average>=90){

grade="A";

}else if(average >=80){

grade="B";

}else if(average >=70){

grade="C";

}else{

grade="F";

}

Score obj=new Score(average,grade);

return obj;

}
