Introducing Loops

A loop is a piece of code in a program that automatically repeats. One complete execution of all statements contained within the loop block is known as an “iteration” or “pass”.

Loops are used in programming to repeat a specific block until some end condition is met. There are three types of loops in C++ programming: for loops, while loops, and do-while loops.

For Loop

The most commonly used loop is the for loop and it is most convenient with its counting loops — i.e. loops that are based on a counting variable, usually a known number of iterations.

Syntax:

for(initialCondition; testExpression; iterativeStatement)…

What’s in an Array?

An array is a variable that can store multiple items of data unlike a regular variable that stores one pierce of data. Just like any variable, arrays must be declared before they can be accessed.

Initializing Arrays

You can initialize a simple array of built-in types, like integers (int) or characters (char), when you first declare the array. After the array name, put an equal sign and a list of comma separated values enclosed in the braces.

int nums[10] = { 0, 10, 20, 30, 40, 50, 60 ,70, 80, 90 }; 

This declared nums to be an array of 10 integers. Remember that the data are stored sequentially in array are elements that are numbered starting at zero. So nums[0] equals to 0, nums[1] equals to 10, and so on. …

Statements

C++ Programs are made up of statements, which are commands that end with a semicolon (;).

The assignment operator
Below, you see a statement assign the variable x to equal the sum of a+ b.

x = a+b;

If statements
Used to control the program flow based on some condition, it’s used to execute some statement code block if the expression is evaluated to true. Otherwise, it will get skipped.

#include <iostream> 
using namespace std;int main() 
{  
    int a = 15, b = 20;   
    if (b > a) {  
    cout << "b is greater" << endl;  
}  
system("PAUSE"); }

Another example is the if statement which evaluates the test expression inside parenthesis. if test expression is evaluated to true, statements inside the body of if is executed. …

Variables

They are the fundamental building block for programming. A variable is a named memory location which temporarily stores data that can change while the program is running.

Defining a Variable
Here is a few ways to define a variable in which you give it a type and a name.

int a;
char b;

You can also give a variable a value on definition.

int c = 10;
char d ='d';

An array is a variable that can store multiple items of data unlike a regular variable which can only store one piece of data. Yes, arrays can be variables.

We will be writing a short series on the basic concepts of C++ such as understanding the main structure of C++ with classes and functions, organizing and sorting using data structures and algorithms, and more about meta-programming, lambda expressions, regular expressions, and testing. For now, let’s start on your first program.

Advantages of C++

C++ is a powerful, efficient and fast language.

• Object-oriented programming language- four principles of object-oriented programming are encapsulation, abstraction, inheritance, and polymorphism. Overall this helps avoids code duplication and increases the code reusability.
• Encapsulation makes data abstraction (security or privacy to data) possible and is achieved with the help of a class. …

First of all, we want to say a BIG THANK YOU to EOS San Francisco, EOS BlockSmith and infinitybloc for organizing such an amazing EXPO!!! Also a thank you to Rose Ren from Obsidian Labs for the heads up and invitation to be part of a panel for the pre-expo event. Inspired to write a short recap to share the wonderful stories and memories from this amazing event.

Friday Night : Meetup at the Starfish Mission SF 🌟

One of us flew out to make it in time to talk on this panel talk: Blockchain Dapp Future and Development, at the Starfish Mission. Phew happy to have made it in time. Thank you to Brandon Parker for recording this! …
