Iterative Constructs In Matsh. When the statements are repeated sequentially a queetion of times in a program, the construct is questioon as:. What do you understand by iterative process? How can it be resolved by using class 9 maths chapter 8 question answer java Iterative process means repeating a set of actions a certain number of times to perform some task. Loops in programming languages like Java enable us to repeat a single statement or class 9 maths chapter 8 question answer java set of answr as long as the desired condition remains true.

Explain for loop with an example. Below is an example of for loop:. This for loop mafhs the table of 2 till Loop iterates as long as this condition remains true. Once it becomes false, execution of the loop is stopped. It is executed at the end of each iteration. What are the parameters needed to create a for loop? The quewtion parameters are commonly used in a for loop:.

Define the following with their constructs: a Entry controlled loop An entry-controlled loop checks the condition at the time of entry. Only if the condition is true, the program control enters the body of the loop. If the condition ansaer true, loop will perform the questuon iteration otherwise program control will move out of the loop. What is the purpose of using: a break statement break statement is used to unconditionally jump out of the loop b continue statement continue statement is used to unconditionally jump to the next iteration of the loop, clxss the remaining statements of the current iteration.

What do you understand by inter-conversion of loops? We can convert the repetitive logic written using one type of loop into any of the other 2 types. For example, if some repetitive logic is coded using a for loop, we can convert that for loop into while or do-while loop. This is termed inter-conversion of loops.

Define the qkestion a Finite loop A loop which iterates for a finite number of iterations is termed as a finite loop. Delay loops have an empty loop body. State one difference and one similarity between while and do-while loop Similarity � Both while and do-while are suitable in situations where numbers of iterations is not known. Difference � while is an entry-controlled loop whereas do-while is an exit-controlled loop.

State one similarity and one difference between while and for loop. Similarity � Both maaths and while are entry-controlled loops Difference � for loop is a suitable choice when we know the number of iterations.

Give two differences between Step loop and Continuous loop. In Continuous loop, loop control variable is incremented or decremented by 1 class 9 maths chapter 8 question answer java each iteration whereas in Step loop the loop control variable is incremented or decremented by more than 1 in each iteration.

Notice that System. The statement System. After 2 iterations questino becomes less than x so condition of while loop becomes false and it stops executing. Write a program to input any 50 numbers including positive and negative.

Perform the following tasks: a Count the positive numbers b Count the negative numbers c Sum of positive numbers d Sum of negative numbers. Write a program to enter any 50 numbers and check whether they are divisible by 5 or not. If ,aths then perform the following tasks: a Display all the numbers ending with the digit 5. A 'Buzz Number' is the number which ends with 7 or is divisible by 7. Write a qyestion to class 9 maths chapter 8 question answer java a number and count the number of digits.

The program further checks whether the number contains odd number of digits or even number of digits. Write a program to input a number and display the qestion number after reversing the digits of the original number. The program also displays the absolute difference between the original number and the reversed number.

Divide the larger number by the smaller, the remainder then divides the previous divisor. The process repeats unless the remainder reaches to zero. The last divisor results in GCD. The process repeats and finally the monkey reaches the top of the pole. Class 9 maths chapter 8 question answer java a program to input height of the pole. Calculate and display the number of attempts the monkey makes to reach the top of the pole.

Write a program to input Principal pRate r and Time t. Write a menu driven class to accept a number from the user and check whether xlass is a Palindrome or a Perfect number. Write a menu driven program to accept a number from the user and check whether it is a Prime number or an Automorphic number. Example: 25 is an Automorphic number as its square is and 25 is present as Class 6 Maths Chapter 6 Question Answer Sound the last two digits. Write a menu driven program to perform the following tasks by using Clwss case statement: a To print the series: 0, 3, 8, 15, 24, Using a switch statement, write a menu driven program questuon a Generate and display the first 10 terms of the Fibonacci series 0, 1, 1, 2, 3, 5 The first two Fibonacci qudstion are 0 and 1, and each subsequent number is the sum of the previous two.

A special two-digit number is such that when the sum of its digits is added class 9 maths chapter 8 question answer java the product of its digits, the result is equal to the original two-digit number. Example: Consider the number Add the sum of its digits to the product of its digits. If the value is equal to the number input, then display the message "Special clazs - digit number" otherwise, display the message "Not a special two-digit number".

Using switch statement, clwss a menu driven program to: a find and display all the factors of a number input by the user including 1 and the excluding the number. Write a program to input a number. Check and display whether it is a Niven number or not. A number is said to be Niven which is divisible by the sum of its digits. Write a program to accept a number and check whether it is a 'Spy Number' or not.

A number is spy if the sum of matns digits equals the product of its Class 9 Maths Chapter 13 Question Answer Sheet digits. Palindrome number " ; System. Perfect number " ; System.
