Question

Introduction to Programming Analyzing algorithms, methods and show the outputs of code. (a) show the output of the following code: public class test: public static void main(string[] args){ double e = 1.0: double item = 1.0: for (int I = 1: 1 50: I = -2){ (I = 2 + i) item = item/1: system.out.println(e): } print out the summation of e starting with 1/2 + 1 until 1/50 + 1. Show the output of the following code: public class test { public static void main(string[] args) { int i = 1: What is the output of the following code:

Explanation / Answer

a) 1+1/1+1/3+1/5 +1/7 +1/9 +1/11 + ...............+1/49

i = 1,3,5,7,9,11,13,15,................,49

Output:

2.410686134642449

b)

   public static void main (String[] args)
   {
       int i =1;
       while(i <= 10)
       {
       method1(1,i);
       i++;
       }
   }
   public static void method1(int i,int num)
   {
   for(int j=1;j<=i;j++)
   {
   System.out.println(num+" ");
   num += 2;
   }
   System.out.println();
   }

Output:
