Input and output of data in different programming languages: comparison and examples

[jewameb621]

All programs, regardless of the programming language, interact with data. One of the key aspects of this work is data input and output. In this article, we will compare how different programming languages ​​handle data input and output, and provide examples to illustrate.

1. C++

In C++, data input is handled using the `iostream` library, which provides `cin` objects for input and `cout` objects for output:

```cpp
#include
using namespace std;

int main() {
int num;
cout << "Enter a algeria telegram data number: ";
cin >> num;
cout << "You entered: " << num << endl;
return 0;
}
```

2. Python

Python has a simple and intuitive syntax for input and output of data:

```python
num = int(input("Enter a number: "))
print("You entered:", num)
```

3. Java

In Java, the `Scanner` class is used for input of data, and `System.out` is used for output:

```java
import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a number: ");
int num = scanner.nextInt();
System.out.println("You entered: " + num);
}
}
