C++

Learning the language C++.

Intro

Create a file with the extension .cpp and write the following lines of code:

  #include <iostream>

  using namespace std;

  int main() {
    char name[32];

    cout<<"Your name: ";
    cin>>name;

    cout<<"✨ Hi "<<name<<"!\n";

    return 0;
  }

Then run the application with Gcc and Make, but feel free to use other tools as you like.

Congratulations! 🎉 🎉 has written your first lines of code in C++. Maybe you still do not understand the instructions of the program well, but little by little it will discover a language to communicate with computers. lets' start! 🚀

Variables

A variable allows to store data, these are usually characters, integers or decimals. In C++ there are reserved words to define a variable type:

Variable type Reserved keyword
Characters char
Integers int
Decimals float, double

Note :

float and double variables both store decimals; your choice will depend on the precision level of the decimals.

Definition of variable types:

  #include <iostream>

  using namespace std;

  int main() {
    char letter;
    int friendsNumber;
    float weight;
    double earthLength;
  }
