Basic output (printing) and inpur (text based) in C++
The standard library defines a handful of stream objects that can be used to access what are considered the standard sources and destinations of characters by the environment where the program runs:
stream | description |
---|---|
cin |
standard input stream |
cout |
standard output stream |
cerr |
standard error (output) stream |
clog |
standard logging (output) stream |
On most program environments, the standard output by default is the screen, and the C++ stream object defined to access it is cout
.
For formatted output operations, cout
is used together with the insertion operator, which is written as <<
(i.e., two “less than” signs).
cout << "Output sentence"; // prints Output sentence on screen
cout << 120; // prints number 120 on screen
cout << x; // prints the value of x on screen
In most program environments, the standard input by default is the keyboard, and the C++ stream object defined to access it is cin
.
For formatted input operations, cin
is used together with the extraction operator, which is written as >>
(i.e., two "greater than" signs). This operator is then followed by the variable where the extracted data is stored. For example:
int age;
cin >> age;

Basic output (printing) and input (text based) in C++
Para imprimir texto o resultados en un programa, es necesario primero pedir al usuario un valor asignado a una variable.
Para esto es necesario cout y cin en los cuales es guardada la variable que indiquemos.
Para empezar debemos incluir la libreria iostream seguido de using namespace std;
Después definimos nuestra funcion principal int main que es lo que el programa va a correr principalmente.
Pedimos al usuario un valor que sera asignado a una variable con un cout, que es lo que va a leer el usuario.
Seguido de esto, el valor que el usuario introduzca con su teclado, se guardará inmediatamente en la variable que ya definimos al principio del int main .
El cin reconoce esta variable que despues va a ser utilizada para realizar los calculos o lo que se tenga que hacer en el programa y finalmente podemos regresar un resultado con otro cout en el cual estará nuestro resultado.
Por ultimo concluimos con un return 0; y guardamos compilamos y corremos el programa.
Aquí esta un ejemplo de ello:
I just made a video explaining how to print on python here it is:
Aqui dejo el link de mi video donde explico rápidamente las formas básicas de entrada y salida de información en C++.

The output is used to print something in the terminal for the user to see it.
