TEA BREAK WITH C++: VARIABLES

Since we learned basic input function at programming with C++, we need to talk a little more about the variables. 

Variables are simply naming some data location in your pc. With variables you can store a value. 

Variables can be global, local or block based. Actually, you can use the same variable name in these locations at the same time. 

  1. #include <iostream>
  2. using namespace std;
  3. int sameVar=1; //defining a global variable at header location
  4. int main(){
  5.     int sameVar=2;    //defining a local variable inside int main
  6.     cout<<“local variable:”<<sameVar; //printing a local variable in int main 
  7.     {
  8.     int sameVar=3; //here we define a variable in any block. 
  9.     cout<<“block variable:”<<sameVar; //printing the block variable
  10. }
  11. //reaching a global variable inside program
  12. cout<<“global variable:”<<::sameVar; //we print global variable in a program
  13. }

 Output;

Here the most important thing we need to talk is the 

variable = value logic. 

Always variable is on the left and the value is on the right of the equivalent sign. 

TEA BREAK WITH C++: INSTALLING IDE

NOTE: You may download codes and extra source material for this book from https://bookofengineering.com/easyseries/

Installing IDE

For all the programming languages the beginning is the printing “Hello World” sentence. So, this is some kind of tradition. But before doing that we need to have the C++ IDE. IDE stands for Integrated Development Environment. So basically, the place where you will communicate with the PC. So, the “language” is coming here. So, for different programming languages there are different environments so that you can talk to your PC and instruct it.

TEA BREAK WITH C++ EASILY WITH THIS EASY BOOK

NOTE: You may download codes and extra source material for this book from https://bookofengineering.com/easyseries/

With this EASY book, I aimed to give the basic programming info as fast as possible without giving so much detail and making you feel bored. Comparing to the other programming books, in this book you will get the essence of the subject, without entering into lots of “unnecessary” details which you may not need to learn at the beginning of learning this language. Especially simple examples are used to show the functions of the codes introduced. I intentionally, tried to keep the text as short as possible so that you can start programming with C++ faster and have time to try it yourself. So this is a great book who wants to start programming as soon as possible and get the idea easily without diving into details.

LEARNING GITHUB

Github is a place where people collaborate to code. You can add people to projects. You can “fork” from other people’s work. You can collaborate with anyone around the world. Version controlling lets you differentiate between different versions. Do you remember giving your code file that you give names like final.cpp, finalfinal.cpp, final2.cpp, thisislast.cpp and goes on. This is the same thing, online.
