Converting bool to text in C++

Question

Maybe this is a dumb question, but is there any way to convert a boolean value to a string such that 1 turns to \"true\" and 0 turns to \"false\"? I could just use an if st

Answer 1

This should be fine:

const char* bool_cast(const bool b) {
    return b ? "true" : "false";
}

But, if you want to do it more C++-ish:

#include 
#include 
#include 
using namespace std;

string bool_cast(const bool b) {
    ostringstream ss;
    ss << boolalpha << b;
    return ss.str();
}

int main() {
    cout << bool_cast(true) << "\n";
    cout << bool_cast(false) << "\n";
}
