Sum of Digits of a Number

Write an algorithm ,a program and draw a flowchart to calculate the sum of digits of any number given by a user.

Step1: Read a number (n) to calculate its sum of digits

Step2: Divide the value of n by 10 and assign it to variable x

Step3: Multiply the value of x by 10 and assign it to variable t

Step4: Subtract the value of t by value of n and assign it to variable c

Step5: Add the value of c & value of sum and assign it to variable sum

Step6: Assign the value of x to variable n

Step7: if x is not equal to zero then go back to step2

Step8: Display “the sum is “, value of variable sum

Step9: Stop

Fibonacci Sequence Flowchart

Fibonacci Sequence Flowchart In the previous video of Fibonacci sequence ,we learned about the Fibonacci series and how to write an algorithm. In this video we will learn how to draw a flowchart for it. First let us write an algorithm for it again. 0,1,1,2,3,5,8,13,21,34,55,89,… Step1: Input the number(n) till which the Fibonacci series will run Step2: Assign the variables a equal to -1 and b equal to 1 Step3: Add the variables a & b and assign it to variable x Step4: Display the value of x Step5: Assign the value of b to variable a Step6: Assign the value of x to variable b Step7: Subtract one from n and store it to variable n Step8: If the value of n is not zero, go back to the Step3 Step9: Fibonacci numbers displayed till n numbers.

Decimal Number to Binary Number

A Binary Number consists of 0 s & 1 s only (Two Digits) whereas a Decimal Number Consists of 0,1,2,3,4,5,6,7,8,9 (ten digits) . For Example ( 111 )2 is binary number equivalent to decimal number ( 7 )10. A bit is a single Binary Digit. The binary number above has three bits. Algorithm Divide the dividend(number) by divisor 2 and get the remainder & the quotient. If the quotient is not zero, then quotient becomes dividend and follow above step. As quotient has now become zero, the binary number is all the remainders from bottom or from right side which consists of 0 & 1.

Prime Numbers

Prime Number is a natural number greater than 1 that has exactly two distinct natural number divisors: 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 13 can only be divided by 1 and by 13 itself. Here is a list of all the prime numbers up to 100: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47, 53,59,61,67,71,73,79,83,89,97,.. 1 is not a prime number as in definition “For a number to be prime it must have two d istinct (different) factors. Algorithm Step1: Input the number(n) to check for prime number Step2: If n is below or equal to 1 then go to step 12 Step3: if n is equal to 2 then go to step 11 Step4: Assign variable count =n / 2 Step5: Assign variable a=1 Step6: Add 1 to a and store it to variable a Step7: remainder = n % a Step8: if remainder=0 then go to step 12 Step9: subtract one from count and store it to variable count Step10: if count is not equal to 0 then go to step 6 Step11
