Answer:
The answer for the given question is :1 1 2 3 5 8 13 21 34 55 89
Explanation:
Initially the variable has been initialized a=0,b=0,c=1,d=1 respectively then next statement will be executed and it will print the value of d i.e 1. After that next statement is executed check the loop condition which is true so it executed the next statement i.e d = b + c so d=0+1 so d=1 after that it changes the value b = c and c = d so b=1 and c=1 and increment the value of a i.e a=a+1 a=1 and printing the value of d .The loop will iterate untill the condition of a is true and same process will follow.
Output :1 1 2 3 5 8 13 21 34 55 89
