Summary
In this episode, Jason introduces std::iota, a C++11 algorithm from the header that initializes a range with sequential increasing values. He demonstrates its basic usage by filling an array with values from 0 to 9, noting that while useful, he personally hasn't found many occasions to use it. Jason then compares std::iota with the older std::generate algorithm combined with C++14 stateful lambdas, showing how this combination provides greater flexibility for generating more complex sequences with custom increments or transformations, while still being optimizable by modern compilers.
