What is Inheritance? tccicomputercoaching.com

Inheritance is a feature of Object Oriented Programming . It is used to specify that one class will get most or all of its features from its parent class. It is a very powerful feature which facilitates users to create a new class with a few or more modification to an existing class. The new class is called child class or derived class and the main class from which it inherits the properties is called base class or parent class.

The child class or derived class inherits the features from the parent class, adding new features to it. It facilitates re-usability of code.

Python Inheritance Syntax

baseclass as per previous example

1. class DerivedClassName(BaseClassName):
2. <statement-1>
3. .
4. .
5. .
6. <statement-N>

Here we always use object of parent type.

object=baseclass()

This child type object will call both module of parent and child.

What is difference between normal variable and reference variable in c++? tccicomputercoaching.com

A reference variable is an alias, that is, another name for an already existing variable in C++ . Once a reference is initialized with avariable, either the variable name or the reference name may be used to refer to the variable .

They can be used like normal variables. '&' operator is needed only at the time of declaration. Also, members of an object reference can be accessed with dot operator ('.'),

For example,

int amount =10;
int rupees;
rupees=&amount;
cout<<"rupess"<< rupess;
cout<<"amount"<< amount;
output:
rupess 10
amount 10
now we do any update in amount variable , it will affect also in rupees variable. Same for vice versa.
for example,
amount=amount + 20;
cout<<rupess;

output: 30

Can we use floating variables in if statements in C?tccicomputercoaching.com

Yes, we can use floating variable in if statement but you have to be very careful while initialising the condition C Language.

Comparisons between floating-point values (including comparisons with zero) are easily sent “off” by truncation/rounding errors.

Yes. You can use. But a direct comparison will never result in a true condition.

Remember that floating point values are hardly precise. So what you can do is along with the float value you are comparing, declare another value that serves as an upper and lower bound to your value,

For example:-

Float a=6.7, b=5.8;
if(a==b)
{
printf("same");
}
Float a=1.0;
If (a==1) // this will be wrong in this case as condition will never be true
To do this correctly you have to write like this
If (a==1.0){
}

2	for loop Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.
3	nested loops You can use one or more loop inside any another while, for or do..while loop.

3 sections of Loop:

1. Initialization:

i=1

2. Codition

i<=10 or i<11

3. Updation(increment/decrement)
