• The program uses the std::inner_product operation to compute the inner product of matrices 1 and 2. It passes the start as well as finish iterators of both vectors together with the starting point of 0.
• The procedure multiplies the elements of both of the vectors that match pairwise, gathers the result knowledge about, and then does it continuously.
• The first value that gets offered is where compounding starts. Finally, the program publishes the determined inner product to the conventional output using std::cout. Once the in-house calculation has been completed, the output will reflect the outcome. This program demonstrates how to use std::inner_product, which offers a straightforward and quick technique for calculating the inner product of two sequences, which can streamline and lessen the repetitive tasks involved in element-wise multiplication and summing. It demonstrates C++'s adaptability to values as a language that's frequently utilized for function calls in libraries that perform mathematical computations on vector information structures.
