a code problem

[husseinballard]

this is a practice question that has me baffled
I am providing my answer, but to tell you the truth I do not see enought info to
answer the question. the question is : fill in the blank linebelow

sum=0;
for(k=0; k<50; k++)
for (j=0; j<7; j++)
sum= sum +______________ __
my answer is sum =sum+ K ++ J ++

but I have been told it was wrong, what is the solution?

You need a semicolon at the end of the line. I can't say much more than that without knowing what this code snippet is trying to accomplish.

The double-plus (++) are almost certainly wrong; although I suppose it might be possible to invent a problem statement that required them.

How does this relate to your almost identical other post? You shouldn't double-post.

You're already incrementing k and j in the for loop, why do it again?
Plus variables are case sensitive, so you need to use j and k, not J and K.

What is sum supposed to be the sum of? Is it supposed to be the sum of itself and J and K?

And why are you double posting?

[crztrane]

My guess would be that sum is meant to be a counter for the number of times gone though the loop so could you try use 1?

sum+ K ++ J ++:
J++ is j=j+1;
k++ is k=k+1
So sum+k++J++ is sum+(k+1)(j+1) then what is the answer

I believe jkmyoung has solved the problem.

[RedSon]

why do you think that?

[holyzuou]

compiler can not identify k++J++

By saying that, I was attempting to encourage someone into providing the correct answer with its logic
