Why isn't this code working though it was working perfectly earlier ???

Question

Here is a code to calculate mean of element stored in a vector data.

float mean= 0.0;
for (int index=0; index <data.size();index ++)
mean = mean + (data[index])/data.size();

At first it gave correct values for mean but
don't know why it gives back 0 as result now.

I think you should write the whole code again on another page. I had similar problems (even though I'm using a different language), and I had to write down the whole code again (not just copy and paste) on another page like... twice or three times, and it worked perfectly again. I know it's tiring but try to bear with it... I hope that helps you.
