Flowchart or Algorithm of Prime, Reverse, Largest Number
Algorithm Prime
Q) Draw the flowchart and write an algorithm to determine whether a number is prime or not.
- This is the algorithm to determine whether a number is prime or not.
- n-Accepted number
- i-loop variable

step 1: start
step 2: [Accept a number] read n
step 3: set i = 2
step 4: Repeat steps 5and 6 until i < n
step 5: [ check whether n is divisible or not]
       if n % i == 0 then
         Goto step7
      Else
         Goto step6
step 6:Â set i = i + 1
step 7:Â if i == n then
        Print “number is prime”
     Else
       Print “number is not prime”
step 8: stop
Algorithm Reverse
Q) Draw the flowchart and write an algorithm to find the reverse of a given number.
- This is the algorithm to print the reverse of an accepted number
- n- Accepted number
- r- variable for remainder
- rev- the reverse of a number

step 1: start
step 2: read n
step 3: Set rev=0
step 4: repeat steps 5,6 & 7 unit n!=0
step 5: set r = n % 10
step 6: set rev = rev*10 + r
step 7: set n=n/10
step 8: print rev
step 9: stop
Algorithm largest
Q) Draw the flowchart and write an algorithm to find the largest of a given number.
- This is the algorithm to find largest of three numbers a,b,c – Accepted numbers

step 1Â Start
step 2Â [Accepted three number]
    read a,b,c,
step 3 if a > b then
      if a > c then
        Print a is the largest
      Else
        Print c is the largest
    Else
     if b > c then
      Print b is the largest
     Else
      Print c is the largest
step 4: stop
