Working with HTTP requests in Python

The internet is made up of a bunch of resources hosted on different servers and interact using HTTP. What is HTTP and how it works? Working with different HTTP requests in Python using the requests library Understanding the information that web resources interact with and use it programmatically

Data Structures

Stack

Stack serves two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed. We have covered functions like top, isFull, isEmpty, peek, pop, push and given an implementation example

Python

Tuple in Python

Tuples in Python are used to hold together multiple objects. Tuples are defined by specifying items separated by commas within an optional pair of parentheses. Any set mutiple comma-separated symbols written default to tuples. Tuples are immutable

C++

Vector in C++

Vector is a sequence container that can store elements, but its size can change dynamically (C/C++ array’s size do not change dynamically). We can store int, string, float elements, depending on how we initialize the vector.

C++

Program Flow control in C++

The flow of control jumps from one part of the program to another, depending on calculations performed in the program. Program statements that cause such jumps are called control statements. We have covered for, while, do while loop, if else, switch, break, continue, goto and functions.

C++

Friend Function in C++

C++ allows a mechanism, in which a non-member function has access permission to the private members of the class. This can be done by declaring a non-member function friend to the class whose private data is to be accessed. The friend is a keyword.

C Programming

Dynamic memory allocation in C

The process of allocating memory at run time is known as dynamic memory allocation. Although C does not inherently have this facility, there are four library routines that can be used for allocating and freeing memory during program execution: malloc, calloc, realloc and free

C Programming

Static memory allocation in C

In C, the default way of memory allocation is static. Static memory allocation is an allocation technique which allocates a fixed amount of memory during compile time and the operating system internally uses a data structure known as Stack to manage it We define static variables and how to delete it
