Question

Write a nested loop to display the following pattern: (Do not write a program)
A B C D
A B C D
A B C D
A B C D

Answer 1

Answer:

Only nested loop:-

int a,b;

for(a=1;a<=4;a++)

{

for(b=65;b<=68;b++)

{

System.out.print((char)b + " ");

}

System.out.println();

}

Description:-

• Variable a and b are initialised
• Condition is checked 1<=4 it is true so body enters the inner loop.
• Inner loop is executed until it is true.First it prints A then B then C then D.
• It will print until the condition is true i.e when 4<=4 now the loop is terminated.
• See the program and output in the attachment.
