The document provides algorithms and flowcharts for: 1) Finding the average of two numbers by inputting the numbers, adding them, and dividing the sum by 2. 2) Summing the even numbers between 1 and 20 by initializing a sum and counter, adding the counter if it is even, and incrementing the counter until it reaches 20. 3) Finding the sum of the first 50 natural numbers by initializing a sum and counter, adding the counter to the sum, and repeating until the sum reaches 50.
Flowchart and algorithm
- 2. Write an algorithm for finding the average of two numbers and also draw a flowchart
- 3. Algorithm: Input: two numbers x and y Output: the average of x and y Step 1 : input x,y Step 2: sum=0,average=0 Step 3:sum = x + y Step 4:average = sum /2 Step 5: print average
- 4. START Input x Sum=average =0 Sum = x + y Average = sum/2 Print Average END
- 5. sums all the even numbers between 1 and 20 inclusive and then displays the sum
- 6. Step 1: start Step 2:sum = 0 ,count = 1 Step 3: if count /2==0 then goto step 4 Step 4:sum = sum + count step 5:count = count + 1 Step 6:if count <20 then go to step 3 step 7: DISPLAY sum Step 8: stop
- 8. To find the sum of first 50 natural numbers. Step 1: start Step 2:sum = 0 ,N= 0 Step 3: N=N+1 Step 4:sum = sum + N step 5:if SUM<50 then go to step 3 Step 6:DISPLAY sum Step 7: stop
- 10. Step 1:start Step 2:Input x, y Step 3:Sum = x + y Step 4:Average = sum/2 Step 5:Output Average Step 6:END
