Output value of true is: 1 value of false is: 0 Example of Boolean (bool) in C++ Here is an example, in which we are assigningfalse,trueand 0 in the variablemarital_status #include<iostream>usingnamespacestd;intmain(){//assigning falseboolmarital_status=false;cout<<"Type1..."<<endl...
The Boolean operators are a bit different than the ones used in algebra because we have to be able to type them. == equal (Remember, a single = is used to assign a value!) < less than > greater than >= greater than or equal to ...
This is clearly explained in the examples given below −// C++ program to demonstrate // bool data type #include <iostream> using namespace std; int main() { bool flag; flag=1;//this is true bool flag1=true; cout<<flag<<" "<<flag1<<endl; int count=0; int x=12; float y=...
Very often, in programming, you will need a data type that can only have one of two values, like: YES / NO ON / OFF TRUE / FALSE For this, C++ has abooldata type, which can take the valuestrue(1) orfalse(0). Boolean Values ...
In the examples below, we use the equal to (==) operator to evaluate an expression:Example int x = 10;cout << (x == 10); // returns 1 (true), because the value of x is equal to 10 Try it Yourself » Example cout << (10 == 15); // returns 0 (false), because 10 ...

In the example below, each string is converted into a Boolean. The text "yoyo" has a true Boolean value while "" and "0" have the false Boolean value. Thus, we can convert the strings into Boolean using PHP’s settype() function. Example Code: function stringToBoolean($str){ settype...
Boolean parameters in a function might be misleading and decrease its readability. If you have a poorly named function like: DoImportantStuff(true, false, true, false); As you can imagine, it’s not clear what all those parameters mean? What’s the first

You can use literals in many contexts, but most commonly to initialize named variables and to pass arguments to functions: C++ Copy const int answer = 42; // integer literal double d = sin(108.87); // floating point literal passed to sin function bool b = true; // boolean literal My...
