Difference b/w Loop

Question

hello how r u guys ? Q: what is the difference between for loop and foreach loop? kindly describe deeply Thanks.

Vulpes · Answer

The essential difference between the two is that: A 'for' loop iterates from an initial value to a final value. The 'step' between iterations can be either fixed or variable. The successive values are held in an iteration variable. A 'foreach' loop iterates over each element of an enumerable collection. The iteration variable holds the actual element. In both cases, you can terminate the iteration early (using 'break') or skip to the next iteration (using 'continue'). More complex variants of the 'for' statement are possible using multiple iteration variables and it's also possible to define an infinite loop like this: for(;;){ // code }
