In a “for” statement, should I use `!=` or `<`?

Question

I\'ve seen both of these two for statements:

for(i=0;i<10;i++) 

for(i=0;i!=10;i++)

I know they all stop when i reaches 10 , bu

Answer 1

Both will work in most situations.

If for some reason the body of code executed in the loop changes i to something greater than 10, the first version will stop looping, but the second will execute forever.
