I want to define array of char in header file:
#define name char[5]
and after to use in this define in struct like this:
struct dog{
name nameOfDog;
int ageOfDog;
};
but it makes me the following error:
"Brackets are not allowed here; to declare an array, place the brackets after the name"
Is there another way to set it to be in the correct syntax?
Thanks!
For arrays in c++ use std::array
#include <array>
#include <string>
struct dog
{
std::array<char,5> name;
unsigned int age;
};
std::string a_string{"Hello"};
For names I wouldn't use an array though but I would use a std::string
You want a type-alias, not a macro. This should work fine in C and C++:
typedef char name[5];
struct dog {
name nameOfDog;
int ageOfDog;
};
You can use using for type alias in C++
#include <iostream>
using name = char[5];
struct dog{
// using name = char[5]; Now, `name` is avaiable only inside the class or
// `dog::name` while using outside the class. https://godbolt.org/z/sr4WYc1Mq
name nameOfDog;
int ageOfDog;
};
int main(){
dog d {"abc", 10};
std::cout << d.nameOfDog << d.ageOfDog;
}
char nameOfDog[5], notchar[5] nameOfDog.int arr[5]{};
