How Can I Effectively Manage Vectors of Arrays in C ?

Understanding the Correct Approach for Vectors of Arrays

Working with a vector of arrays in C presents challenges due to the inherent characteristics of arrays, which are neither copy-constructible nor assignable. This leads to errors when attempting to resize a vector containing arrays, as the conversion from an integer to a non-scalar array type is not allowed.

The Solution: Array Class Templates

To overcome this limitation, array class templates can be employed. These templates encapsulate the functionality of arrays while adhering to the requirements of containers. Consider the following example:

std::vector<std::array<double, 4>>

Here, the std::array template provides an array-like class that adheres to the necessary principles. The vector can now store elements of type std::array, allowing for efficient resizing and manipulation.

Alternative Options

Aside from array class templates, consider the following options:

• Boost.Array: This library offers an array class template that provides additional features and optimizations.
• std::tr1::array: A standardized array class template from the C Technical Report 1.

Custom Array: Implementing your array class template is relatively straightforward and can provide greater customization options.

By utilizing array class templates, you can effectively manage vectors of arrays while maintaining the desired functionality and adherence to language specifications.
