Occuring TLE errors in cb ide and syntax errors in coding block software

#1


Please look into i wrote this program watching prime factorization video of tutorial from course it still gives TLE in ide and syntax error in coding block software.???

#2

Change line 9 to
for(int i=3;i*i<=n;i+=2)

Now it doesn’t throw segmentation fault.

#3

please also tell me the reason behind doing so

#4

I want was going wrong?? with only i??

#5

your i and j variable are int,
Now when i equals n, and j equals n*n, that causes integer overflow and thus the problem.
So restrict i to sqrt(n)
