— And sqrt mb ?

— Also you should move than int d=2; into the for, like so:
for(int d = 2; d <= a; d++)

— Yep

— If he's testing small numbers it might be slower, but for anything slighly larger, yes

— 

Steve if a number isn't divisable (with a remainder of 0) by any of the numbers smaller than it's square root, it's prime

— So you're doing some unnecessary checks

— The condition can also be d*d<=a

— But still getting error when i run

— Well what's the error?

— Can someone please send me the code

— No, tell us the error

— This

— You're missing an init statement

— ^

— And also your logic isn't correct
