I still prefer using std::vector<\/code> although this question mentions “without using vector”. But let’s just try doing so with array anyway.<\/p>\n

int int_array[20] = {\/*...*\/};\n\nint* last_ptr = std::remove(std::begin(int_array), std::end(int_array), 0);\n\nfor (int* it = int_array ; it != last_ptr ; ++it)\n    cout << *it << endl;\n<\/code><\/pre>\n
As convention, the resulting last_ptr<\/code> points to the location one pass the end of the resulting array.<\/p>\n
Since it is an array, the actual array size does not change. All we can do is to ignore the unused part of the array.<\/p>\n<\/p><\/div>\n
