chapter 1. Introduction to computer and programming


Question 1. Draw a flow chart to do the sum of 10 elements read from the user.



Question 2. Write an algorithm and draw a flowchart to print first N Fibonacci numbers.

  1. Start
  2. Declare variables i, a,b , show
  3. Initialize the variables, a=0, b=1, and show =0
  4. Enter the number of terms of Fibonacci series to be printed
  5. Print First two terms of series
  6. Use loop for the following steps
        -> show=a+b
        -> a=b
        -> b=show
        -> increase value of i each time by 1
        -> print the value of show
  7. End

Question 3. Write an algorithm for finding odd and even number from given two numbers.

        Step 1 : Start
        Start 2 : Read n
        Start 3 : if (n%2 == 0), Write " even number" else Write " odd number"
        Start 4 : Stop

Question 4. Draw flowchart menu driven C program for simple calculator.  



Question 5. Write an algorithm and draw the flow chart to find the largest of the given three numbers – A, B and C.

Algorithm:

        Step 1 : Start
        Start 2 : Input a, b, c
        Start 3 : if a > b goto step 4, otherwise goto step 5
        Start 4 : if a > c goto step 6, otherwise goto step 8
        Start 5 : if b > c goto step 7, otherwise goto step 8
        Start 6 : Output "a is the largest", goto step 9
        Start 7 : Output "b is the largest", goto step 9
        Start 8 : Output " c is the largest", goto step 9
        Start 9 : Stop
