for_each(C++)

for_each -- apply a given function to every location in an array

Synopsis

   template <class T>
   void for_each(void (*fun)(T*),T b,T* e);

Assumptions

None.

Description

Applies fun to every location in the array from the leftmost to the rightmost.

Complexity

If N is the size of the array, then complexity is O(N). Exactly N calls to fun are made.

Notes

Because a Block (see Block(3C++)) can always be used wherever an array is called for, Array Algorithms can also be used with Blocks. In fact, these two components were actually designed to be used together.
