How to map C++ enums to strings?
Here we will see how to map some enum type data to a string in C++. There is no such direct function to do so. But we can create our own function to convert enum to string.
We shall create a function that takes an enum value as the argument, and we manually return the enum names as a string from that function.
Example Code
#include <iostream>
using namespace std;
enum Animal {Tiger, Elephant, Bat, Dog, Cat, Mouse};
string enum_to_string(Animal type) {
switch(type) {
case Tiger:
return "Tiger";
case Elephant:
return "Elephant";
case Bat:
return "Bat";
case Dog:
return "Dog";
case Cat:
return "Cat";
case Mouse:
return "Mouse";
default:
return "Invalid animal";
}
}
int main() {
cout << "The Animal is : " << enum_to_string(Dog) << " Its number: " << Dog <<endl;
cout << "The Animal is : " << enum_to_string(Mouse) << " Its number: " << Mouse << endl;
cout << "The Animal is : " << enum_to_string(Elephant) << " Its number: " << Elephant;
}Output
The Animal is : Dog Its number: 3 The Animal is : Mouse Its number: 5 The Animal is : Elephant Its number: 1
