    // cout<<"the value of d is "<<d<<endl<<"the value of e is: "<<e<<endl;
    // // 34.43 is in the form of longdouble so is we want to convert into float use
    // // this (34.43f)
    // // In the same way you can convert double int float by (34.43l)
    
    //     cout<< "The size of 34.43 is: "<<sizeof(34.43)<<endl;
    //     cout<< "The size of 34.43f is: "<<sizeof(34.43f)<<endl;
    //     cout<< "The size of 34.43F is: "<<sizeof(34.43F)<<endl;

    //     cout<< "The size of 34.43L is: "<<sizeof(34.43L);

    // ************ Refrence Variable**************** 

    // float x = 555 ; 
    // float & y = x ;
    // cout<<x<<endl;
    // cout<<y;

    // ************   Type casting **************
    //  it change the type of variable or 
    // it change one data type to other data type    

//     int f = 34;
//     float h = 34.43 ;

//     cout<<"The value is "<<(float)f<<endl;
//     cout<<"The value is "<<(int)h<<endl;  // or you can write int(a)
//     int c = int(h);
//     cout<<c;

//     cout<<"The sume of  a and b is: "<<f+h<<endl;
//     cout<<"The sume of  a and b is: "<<f+int(h)<<endl;
//     cout<<"The sume of  a and b is: "<<f+(int)h<<endl;
