How do you represent a boolean as a %_

Question

eg for int its %d, String %s

Answer 1

bool is 1 or 0, but maybe you can fake it?
printf("%s", x?"true":"false")

or create a macro:
#define fBool(b)((b)?"true":"false")

x= 3<5;
printf("%s", fBool(x))

Answer 3

#include <stdio.h>
#include <stdbool.h>

int main(void) {
bool x = true; /* equivalent to bool x = 1; */
bool y = false; /* equivalent to bool y = 0; */
if (x) /* Functionally equivalent to if (x != 0) or if (x != false) */
{
puts("This will print!");
}
if (!y) /* Functionally equivalent to if (y == 0) or if (y == false) */
{
puts("This will also print!");
}
}

/* c++ have std::boolalpha , std::noboolapha*/

#include<iostream>
using namespace std;

int main()
{
cout<<"when boolalpha flag is off\n";
cout<<"true: "<<true<<endl;
cout<<"false: "<<false<<endl;

cout<<"when boolalpha flag is on\n";
cout<<boolalpha<<"true: "<<true<<endl;
cout<<boolalpha<<"false: "<<false<<endl;
cout<<noboolalpha;
}
