Does C have a “foreach” loop construct?

Question

Almost all languages have a foreach loop or something similar. Does C have one? Can you post some example code?

Answer 1

While C does not have a for each construct, it has always had an idiomatic representation for one past the end of an array (&arr)[1]. This allows you to write a simple idiomatic for each loop as follows:

int arr[] = {1,2,3,4,5};
for(int *a = arr; a < (&arr)[1]; ++a)
    printf("%d\n", *a);
