Py: 6. Python Lists


A list in Python is used to store the sequence of various types of data. Python lists are mutable type its mean we can modify its element after it created. The items in the list are separated with the comma (,) and enclosed with the square brackets [].

Syntax:-
L1 = ["Mohit", 102, "INDIA"]   

List Indexing and Slicing
The indexing is processed in the same way as it happens with the strings. The elements of the list can be accessed by using the slice operator [].

The index starts from 0 and goes to length - 1. 

Example:- 
list = [1,2,3,4,5,6,7]  
print(list[0])  
print(list[1])  
print(list[2])  
print(list[3])  
# Slicing the elements  
print(list[0:6])  
# By default the index value is 0 so its starts from the 0th element and go for index -1.  
print(list[:])  
print(list[2:5])  
print(list[1:6:2])  

Output:-

C: 10. Array

 An array is defined as the collection of similar type of data items stored at contiguous memory locations. For example, if we want to store the marks of a student in 6 subjects, then we don't need to define different variables for the marks in the different subject. Instead of that, we can define an array which can store the marks in each subject at the contiguous memory locations. An array index starts with 0. Syntax:- data_type array_name[array_size];   int marks[5];     Example:- #include<stdio.h>   int main(){       int i=0;     int marks[5];//declaration of array        marks[0]=80;//initialization of array     marks[1]=60;     marks[2]=70;     marks[3]=85;     marks[4]=75;     //traversal of array     for(i=0;i<5;i++){       printf("%d \n",marks[i]);   ...

C++: 7. Inheritance

In C++, inheritance is a process in which one object acquires all the properties and behaviors of its parent object automatically. In such way, you can reuse, extend or modify the attributes and behaviors which are defined in other class. In C++, the class which inherits the members of another class is called derived class and the class whose members are inherited is called base class. The derived class is the specialized class for the base class. Single Level Inheritance When one class inherits another class, it is known as single level inheritance. Example:-  #include <iostream>   using namespace std;    class Account {      public:      float salary = 60000;     };      class Programmer: public Account {      public:      float bonus = 5000;        };        int main(void) {   ...
