Answer :

Here's one possible algorithm to print even numbers from 1 to 100:


Start with a variable i equal to 1.

Check if i is less than or equal to 100.

If i is less than or equal to 100, check if i is even (i.e. if i is divisible by 2 with no remainder).

If i is even, print i.

Increment i by 1.

Go back to step 2.

End the program.

                                                /    \

                                             /          \

                                            v            v

                                            i = 1      i <= 100

                                                \    /

                                                 v  v

                                                 i%2==0?

                                                /    \

                                               /      \

                                              /        \

                                             /          \

                                            v            v

                                            print i     i++

                                             \          /

                                              \        /

                                               \      /

                                               

                                           v
                                           goto 2
                                           
                                           end

This flowchart shows how the algorithm starts by initializing a variable `i` to 1 and then proceeds to check if `i` is less than or equal to 100 in a loop. If `i` is less than or equal to 100, it checks whether `i` is even or not by checking the remainder when divided by 2. If `i` is even, it prints the value of `i` and increments `i` by 1. The loop continues until `i` is greater than 100, and the program ends.
