How Can I Efficiently Store Arrays Within a C Vector?

An Effective Approach to Handling Vectors of Arrays

When working with data structures in C , it is important to understand the limitations and requirements of different container types. One common issue encountered when working with vectors is the inability to store arrays directly within them. This is because arrays lack certain properties that are essential for use within containers, such as copy constructibility and assignability.

To resolve this issue and effectively store arrays within a vector, one can utilize an array class template. This template provides a type that behaves like an array but possesses the necessary characteristics for use within containers.

Utilizing Array Class Templates

Array class templates, such as those provided by Boost, TR1, or C 0x, can be employed to create vectors of arrays. These templates offer a type equivalent to std::array that is copy constructible and assignable.

For example, to define a vector of arrays using the std::array template, the following syntax can be used:

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

By replacing std::array with std::tr1::array or boost::array, the code can be adapted to use the templates provided by TR1 or Boost, respectively. Alternatively, one can implement their own array class template.

Conclusion

Employing array class templates provides a solution to the challenge of storing arrays within vectors. These templates endow the array type with the requisite properties for seamless integration with containers, enabling effective data management and manipulation.
