# Fast I/O Library for C++

This library provides a highly optimized alternative to the standard I/O operations (`cin`, `cout`, `scanf()`, `printf()`) in C++. By significantly reducing the overhead associated with these operations, `fistream` and `fostream` classes can perform input and output operations up to 10 times faster, making it particularly useful for performance-critical applications such as competitive programming, large data processing, and more.

## Features

- Enhanced Performance: Achieve faster I/O by minimizing internal operation overhead.

- Ease of Use: Implements standard C++ stream operators, making it easy to integrate and replace existing code with minimal changes.

- Extended Compatibility: Supports all fundamental data types and offers precision control for floating-point numbers.

## Usage

`#include "fiostream_x86/64.h"` in your C++ project and replace `cin` and `cout`, with `fin` and `fout`.

```cpp

#include "fiostream_x86.h"

int main()

{

    int a, b;

    fin >> a >> b; // Reading integers using fistream

    fout << "Sum is: " << (a + b) << fendl; // Writing output using fostream

    return 0;

}

```

### Input

```cpp

int x;

double y;

fin >> x >> y; // Read an integer and a double

```

### Output

```cpp

int num = 42;

fout << "Number: " << num << fendl;

long double pi = acosl(-1);

fout << "Pi: " << fsetprecision(20) << pi << fendl;

```

## Caution

Don't use `fin` and `fout` inconsistently with `cin`, `cout`, `scanf()` or `printf()` because it can be a cause of potential errors.
