    That's a very open ended question.... You can use them in many, many scenarios..

    AND/OR/NOT are represented as operators: &&/||/! respectively.. true and false are both keywords (false represents Zero, and true typically represents One), and are generally the 2 possible outcomes of any expression involving these operators.

    Alright if you know how to use them then what are you doing here?
    if you need examples you should know from what your getting the knoledge from.

    //Enouph of the flame
    Alright here are some examples.

    Code:
    #include <iostream>//Basic Library
    using namespace std;// Namespace for not typing out the whole function like so std::cout// 
    
    int main(){// You need int main for compiler even to read this.
    int i=0,a=0; // Numbers only Thats 6 digit limit//
    bool event; // True and False//
    if(i==0 &&/* && means AND*/ a==0){ // example of AND
    event=true;// example of True 
    event=false;//Example of false
    }
    if(event==true || event==false){ // example of or
    i=1;
    }
    if(i != 0){//Example of Not
    cout<<"i does not equal 0"<<endl;// This is Outputing whats inside of quotes//
    system("PAUSE");// This pauses the system for you to see ouput //
    }
    }
    its untested but those are examples

    right, first off. Learn to spell. if you can't even spell, coding is not for you. But I don't believe you can't spell, I think you're just being lazy.
    I'll give you some starters:
    - '2' is a number. 'to' is a word. They have different meanings.
    - there is no such word in the english language as '-n-'. The word is
    'and', and it takes the same amount of time to type!

    edit: and if you still can't spell, use a spell checker!

    You might think, I'm being pedantic (or just being an ..............), but when you code, if you make a speeling mistock, your code won't work.

    as for your question, boolean logic (true, false, and, or, etc) is used to make decisions in a program.

    Code:
    int age = 20;
    
    if (age < 10) // evaluates to true
    {
        cout << "you are young"; // this means print "you are young" on the screen
    }
    
    else if (age >= 10 && age < 20) // this means if the age is greater than 10 AND less than 20
    {
        cout << "you are an adolescent";
    }
