Segmentation Fault

#1

Sir, in prime visits question if I take i and j as int in line number 16 and 20 respectively then I am getting segmentation fault. Why?

Here is the code-https://ide.codingblocks.com/s/650524

this is because
i * i will overflow the int

for (ll j = i * i; j <= 1000000; j = j + i ) {

                p[j] = 0;

            }
