That day's question is quite simple Next let's take a look 　　No1 If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. //project euler num1#include The first question is very simple. Don'

The foreach statement repeats an embedded statement group for each element in an array or an object set. The foreach statement is used to cyclically access the set to obtain the required information, but should not be used to change the set content to avoid unpredictable side effects.
