C++ Program For Boolean to String Conversion
Last Updated :

In this article, we will see how to convert a boolean to a string using a C++ program.
In boolean algebra, there are only two values 0 and 1 which represent False and True. Thus, boolean to string conversion can be stated as:
Boolean -> String
Example:
Input: 1
Output: True
Methods to Convert a Boolean to a String in C++
There are 2 ways to convert boolean to string in C++:
- Using Customized Boolean To String Conversion Function.
- Using Alphanumeric Boolean Values.
Let’s discuss each of these methods in detail.
1. Boolean To String Conversion Using Customized Function
We have defined a customized boolean-to-string conversion function btos(). It is responsible for converting a boolean value into its corresponding string representation.
C++ Program to Convert Boolean Values to String
C++
#include <iostream>
using namespace std;
string btos( bool x)
{
if (x)
return "True" ;
return "False" ;
}
int main()
{
cout << 1 << " || " << 0 << " is " << btos(1 || 0)
<< endl;
cout << 1 << " && " << 0 << " is " << btos(1 && 0)
<< endl;
return 0;
}
|
Output
1 || 0 is True
1 && 0 is False
Complexity Analysis
- Time complexity: O(1)
- Auxiliary space: O(1)
2. Using Alphanumeric Boolean Values
The boolalpha flag indicates whether to use textual representation for bool values viz true or false or to use integral values for bool values viz 1 or 0. When the boolalpha flag is set, the textual representation is used and when it is not set, integral representation is used. By default, it is not set.
C++ Program to Convert a Boolean to a String Using boolalpha Flag
C++
#include <iostream>
using namespace std;
int main()
{
bool value = true ;
cout << "Printing true value before boolalpha: "
<< value << endl;
cout << "Printing true value after boolalpha: "
<< boolalpha << value << endl;
return 0;
}
|
Output
Printing true value before boolalpha: 1
Printing true value after boolalpha: true
Complexity Analysis
- Time complexity: O(1)
- Auxiliary space: O(1)
