c++ print vector without loop

To print a vector in C++ without using a loop, you can utilize the std::for_each algorithm from the <algorithm> header along with a lambda function. Here are the steps to achieve this:

1. Include the necessary header files:

#include <iostream>
#include <vector>
#include <algorithm>

1. Create a function or lambda that will print each element of the vector. In this case, we will use a lambda function:

auto printElement = [](const int& element) {
    std::cout << element << " ";
};

1. Create a vector and populate it with some values:

std::vector<int> myVector = {1, 2, 3, 4, 5};

1. Use the std::for_each algorithm to apply the lambda function to each element of the vector:

std::for_each(myVector.begin(), myVector.end(), printElement);

1. Finally, add a newline after printing all the elements:

std::cout << std::endl;

The complete code would look like this:

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    auto printElement = [](const int& element) {
        std::cout << element << " ";
    };

    std::vector<int> myVector = {1, 2, 3, 4, 5};

    std::for_each(myVector.begin(), myVector.end(), printElement);

    std::cout << std::endl;

    return 0;
}

When run, this code will print the elements of the vector without using a loop. The lambda function printElement is applied to each element of the vector using std::for_each, and the elements are printed with a space delimiter. The newline at the end ensures that the output is properly formatted.
