C++程序将布尔变量转换为字符串

bool input = <Boolean value>;
string output = input ? "true" : "false";

#include <iostream>
using namespace std;
string solve(bool input) {
   //using ternary operators
   return input ? "true" : "false";
}
int main() {
   bool ip = true;
   string op = solve(ip);
   cout<< "The input value is: " << ip << endl;
   cout<< "The output value is: " << op << endl;
   return 0;
}

The input value is: 1
The output value is: true

bool input = <Boolean value>;
cout<< "The output value is: " << boolalpha << input << endl;

#include <iostream>
using namespace std;
int main() {
   bool ip = true;
   cout<< "The input value is: " << ip << endl;
   cout<< "The output value is: " << boolalpha << ip << endl;
   return 0;
}

The input value is: 1
The output value is: true

bool input = <Boolean value>;
ostringstream oss;
oss << boolalpha << ip;
string output = oss.str();

#include <iostream>
#include <sstream>

using namespace std;
string solve(bool ip) {
   
   //using outputstream and modifying the value in the stream
   ostringstream oss;
   oss << boolalpha << ip;
   return oss.str();
}

int main() {
   bool ip = false;
   string op = solve(ip);
   cout<< "The input value is: " << ip << endl;
   cout<< "The output value is: " << op << endl;
   return 0;
}

The input value is: 0
The output value is: false
