Question

Creating a program for pattern making is an important aspect of logical development. Kunal has tried to design a program for a pattern shown alongside. But, due to some confusion, he could not complete it and has left some places blank marked with ?1?, ?2?, ?3? and ?4? to be filled with appropriate value/ expression. The program is as shown below: 

ZZZZZ XXXX VVV TT R

class Pattern
{
     public static void main()
     {
       int a, b, p;
       p = ..........?1?.........;
       for (a = 5; a >= 1; a--)
       {
          for(............?2?...............)
          System.out.print((...?3?...)p);
          System.out.println();
          p = .....?4?......;
       }
     }
}

Based on the above discussion, answer the following questions:

1. What will be filled in the place marked with ?1?
   1. 65
   2. 82
   3. 90
   4. 122
2. What will be filled in the place marked with ?2?
   1. b = 1; b <= a; b++
   2. b = a; b < 90; b++
   3. b = 90; b > 65; b++
   4. b = 65; b <= 90; b++
3. What will be filled in the place marked with ?3?
   1. int
   2. char
   3. float
   4. double
4. What will be filled in the place marked with ?4?
   1. p + 2
   2. p * 2
   3. p++
   4. p − 2

Answer 1

1. iii. 90
2. i. b = 1; b <= a; b++
3. i. char
4. iv. 
5. iv. p − 2
