Question

1.Modify your program by enclosing your loop in another loop so that you can find consecutive sums. For example , if 5 is entered, you will find five sum of consecutive numbers:

1 = 1
1+2 = 3
1+2+3 =6
1+2+3+4 =10
1+2+3+4+5 =15

Print only each sum, not the arithmetic expression

2. Decision Structures and Boolean Logic

1. Write an if statement that assigns 20 to the variable y and assigns 40 to the variable z if the variable x is greater than 100.
2. Write an if statement that assigns 0 to the variable b and assigns 1 to the variable c if the variable a is less than 10.
3. Write an if-else statement that assigns 0 to the variable b if the variable a is less than 10.
Otherwise, it should assign 99 to the variable b.

Explanation / Answer

1.) import java.io.*;
   class Sum
   {
       public static void main(String args[])throws IOException
           {
           BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
           System.out.println("Enter your number:");
           int input=Integer.parseInt(br.readLine());
           int sum=0,i=0,j=0;
           for(i=1;i<=input;i++)
               {
               sum=0;
               for(j=1;j<=i;j++)
                   {
                   sum=sum+j;
                   }
                   System.out.println(j);
               }
           }
   }      

2.) 1.) if(x>100)
       {
       y=20;
       z=40;
       }
      
   2.) if(a<10)
       {
       b=0;
       c=1;
       }
      
   3.) if(a<10)
           b=0;
       else
           b=99;
