It depends; there is no right or wrong answer. Take into account the size of the numbers involved, the amount of space you have, and the type of numbers that would make sense, both with the numbers involved and in a practical sense - your numbers may all be multiples of seven, but don't make it harder than it needs to be. There are honestly a countless number of variables involved, so mostly it's up to you to decide what makes sense.
you use a graph to see your progress
Any graph can use percentages.
You can definitely use a table or graph to what your findings. You can use a bar graph for this purpose for example.

a circle graph is the best graph to use for that!!
Incremented.
Yes, you can have multiple expressions in the increment poart of the for loop statement. Just use the comma, and each expression will be evaluated from left to right.

You can use a table or a graph to organize you findings.
int a, b; b = 5; /* post-increment operator */ a = b++; /* a is now 5, and b is now 6. */ /* pre-increment operator */ a = ++b; /* a and b are now both 7 */
I assume by 2 plus you really mean ++. This is the increment operator which is used to increment the operand. If placed before the operand, the operator evaluates the incremented operand (prefix increment). If placed after the operand, the operator evaluates the non-incremented operand (postfix increment). +++ and ++++ are meaningless but are assumed to mean incrementing an increment. If you wish to increment an increment, you must use the compound expression ++(++) or (++)++. Thus for the variable x, prefix incrementing twice would be achieved with ++(++x), while postfix incrementing twice would be achieved with (x++)++. You can also mix the two, such as ++(x++) or (++x)++, both of which would increment x twice but would evaluate the increment of x. If postfix increment is not a requirement, it would be much easier to use the compound expression x+=n, where n is the amount you wish to increment. This is the same as saying x=x+n.
They use the binary code (1010101011001100)

You can use a bar graph or a line graph.
