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))

#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; }
