These functions are available in C++ and beyond.

Interesting functions:

• all_of / any_of / none_of
• for_each
• count_if
• find_if
• genrate
• shuffle
• nth_element
• equal_range
• inplace_range
• minmax_element
• partial_sum
• adajacent_difference

For examples for these functions, check the folowwing resources:

all_of / any_of / none_of

std::vector<int> collection = {3, 6, 12, 6, 9, 12};

// Are all numbers divisible by 3?
bool divby3 = std::all_of(begin(collection), end(collection), [](int x) {
    return x % 3 == 0;
});
// divby3 equals true, because all numbers are divisible by 3

// Is any number divisible by 2?
bool divby2 = std::any_of(begin(collection), end(collection), [](int x) {
    return x % 2 == 0;
});
// divby2 equals true because 6, 12 divisible by 2

// Is no number divisible by 6?
bool divby6 = std::none_of(begin(collection), end(collection), [](int x) {
    return x % 6 == 0;
});
// divby6 equals false because 6, 12 divisible by 6
