Difference between evaluation of while(n>0) and while(n!=0)

Question

Is the evaluation of while(n>0) and while(n!=0) different? Basically both are to exit in the same condition. So is there a scenario when one of them should be used? Or will it make a difference in the performance efficiency by changing the loop condition when the number of times the loop being evaluated being the same?

Answer 1

This depends on your platform, but in general, it will perform identically. For example, for x86 architecture cmp operator will be used for both > or !=. Here you can read more.
