Question

Draw a flow chart and write an algorithm for a programm that adds all 2 digit numbers divisible by 3.( Hint: these numbers are 12,15 till 99.you must use looping)

Answer 1

Answer:

Algorithm:

Step 1:  Input N  // the number up to which we need to count , here it is 99

Step 2:  Sum = 0  

Step 3:  for(i= 0;i<=N;i++)

Step 4: if ( i %3 == 0)

         Sum = Sum + i;

           }

Step 5:  Print Sum

Flowchart:

Start -> Sum = 0 -> Read N -> i<=N-> if ( i %3 == 0)-> true->Sum = Sum + i-> i++->  Sum = Sum + i-> Print Sum              |

                                                                   v

                                                                    false-> i++
