Boolean variables are variables which can store conditional values, i.e. true, false (1, 0). #include <iostream> using namespace std; int main() { bool ident = false; int cookies; cout << "Please input number of cookies." << endl; cin >> cookies; if (cookies > 10) { ident = true; } if (ident) { cout << "So cookies. Much wow." << endl; } else { cout << "Not wow." << endl; } return 0; }

Boolean (often shortened to bool) are a data type that can only hold 2 states, namely true, and false. They can be used directly into conditional statements, and are generally extremely useful for controlling the flow of the program.

@Mich You'll often find yourself wanting to make your program behave differently depending on conditions, and Boolean values (stored in variables, literals, or returned by functions/properties) are fundamental in making your program automatically decide how to behave.

//two boolean variables: one true, one false bool trueVar = true; //first variable bool falseVar = false; //second variable //evaluate if ifrst variable is true if (trueVar==true){ cout<<"the fisrt variable is true"; } //evaluate if second variable is true if (falseVar==true){ cout<<"the second variable is true"; }else{ //if second variable is not true cout<<"the second variable is false"; } Output will be the first variable is true the second variable is false

boolean is a data type of size 1 byte in c++. boolean only contain two values true (1) and false (0).This type of data type is used when we want to deal with true and false.

Dao, in what circumstances would we need to control flow? what do you mean by flow of the program?
