I have the below code which uses enum value to initialize the vector of the struct. I was getting the error regarding narrow conversion. I have referred the Microsoft doc : link by which I can solve the issue by below code.
#include <iostream>
#include <vector>
#include <string>
enum NUMBERS
{
NUMBERS_ZERO = 0xA0000000,
NUMBERS_ONE = 0xA0000001,
NUMBERS_TWO = 0xA0000002,
NUMBERS_THREE = 0xA0000003,
};
struct Person {
uint32_t m_id = 0;
std::string m_name;
Person(uint32_t id, std::string name) :
m_id(id), m_name(name) {}
};
std::vector<Person> PersonList =
{
{static_cast<uint32_t>(NUMBERS_ZERO), "abc"},
{static_cast<uint32_t>(NUMBERS_ONE), "pqr"},
{static_cast<uint32_t>(NUMBERS_TWO), "xyz"},
{static_cast<uint32_t>(NUMBERS_THREE), "zzz"}
};
int main()
{
for (auto it : PersonList)
std::cout << it.m_id << " : " << it.m_name << "\n";
return 0;
}
Since we can see the above initialization of vector with typecasting looks weird/complex. How can I improve the code with more readability. I have tried the below code, but it throws error: Conversion from 'Numbers' to 'uint32_t' requires a narrow conversion.
Any suggestion would be appreciated.
/*
struct Person {
uint32_t m_id = 0;
std::string m_name;
Person(uint32_t id, std::string name) :
m_id(static_cast<uint32_t>(id)), m_name(name) {}
};
std::vector<Person> PersonList =
{
{NUMBERS_ZERO, "abc"},
{NUMBERS_ONE, "pqr"},
{NUMBERS_TWO, "xyz"},
{NUMBERS_THREE, "zzz"}
};
*/
