//BY CODIVAS
//here we'll dicuss the code of 2nd class:
// The topic mainly we've covered are:
//if statement
// if..else statements
// nested if statements
// if-else-if ladder

    // from line 14 to 6 => if statements

   }
 //from line 12 to 17 => if else statements

    //nested if else statements => when we are using if inside another if (as it shown below)
    //from line 21 to 24  => nested if statements / 21 to 31 => nested if else statements

     // see the code written below
     // from line 36 to 44 => if-else-if ladder ----> first it'll go on "if" condition if it is false then it'll check the "else if" condition if it's false too then it'll print the "else cndition"
