Here’s a simplistic implementation of what you asking. #include <stddef.h> #include <stdlib.h> #include <stdio.h> int normalize_weights(double *weights, size_t num_weights) { double sum = 0; for (size_t i = 0; i < num_weights; ++i) { if (weights[i] < 0) return -1; sum += weights[i]; } if (sum == 0) return -1; for (size_t i = 0; … Read more
Introduction A decaying average is a type of moving average that gives more weight to recent data points and less weight to older data points. This type of average is useful for tracking trends in data that changes over time. In this article, we will discuss how to calculate a decaying average and provide an … Read more

First, char *stuff_to_append_to[] is an array of pointers of undetermined length, that is not a valid parameter, as the last dimension of an array must be specified when passed to a function, otherwise, pass a pointer to type. Next, char **stuff_to_append is a pointer to pointer to char and is completely valid, but given your … Read more
