How to apply function that returns Result to each element of HashSet in Rust

As a language that aims for safety and performance, Rust provides a powerful data structure called HashSet that provides a fast and efficient way to store and retrieve unique values. HashSet is optimized for scenarios where you need to check for the presence of a value and avoid duplicates, making it a popular choice among… Read More How to apply function that returns Result to each element of HashSet in Rust

Initializing multiple of the same structs with the same values in C

I made a struct with a few members and want to create multiple structure variables with the same initial member values. My struct is the following: struct tempSens { float temperature; volatile int updateTimer; }; I want to make 2 structure variables TS1 and TS2 that both initialize their members with .temperature = 40.0 and… Read More Initializing multiple of the same structs with the same values in C

Using pointers when they are elements of a structure array in C

I want to check if the string SET_NAME is the name of an existing set, and if so, SET1 will point to the address of that set. #include <stdio.h> #include <ctype.h> #include <string.h> #include <stdlib.h> typedef unsigned char set[16]; int main(){ char set_name[5] = {‘0’}; char *set1; int i; set_name[0] = ‘S’; set_name[1] = ‘E’;… Read More Using pointers when they are elements of a structure array in C
