cpp struct initialization code example

Example 1: c++ 20 struct initialization

#include <iostream>
#include <filesystem>

struct hello_world {
    const char* hello;
    const char* world;
};

int main () 
{
    hello_world hw = {
        .hello = "hello, ",
        .world = "world!"
    };

    std::cout << hw.hello << hw.world << std::endl;
    return 0;
}

Example 2: how to initialize an struct object in c++

// exemple avec la structure Coordonnees :
struct Coordonnees
{
  int x;
  int y;
}

int main()
{
  Coordonnees coords = {1,2};
}

Example 3: c++ initialize a struct

struct address {
    int street_no;
    char *street_name;
    char *city;
    char *prov;
    char *postal_code;
};

address temp_address = {
  0,  // street_no
  nullptr,  // street_name
  "Hamilton",  // city
  "Ontario",  // prov
  nullptr,  // postal_code
};
