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.
- 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.
#include "fiostream_x86/64.h" in your C++ project and replace cin and cout, with fin and fout.
#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;
}int x;
double y;
fin >> x >> y; // Read an integer and a doubleint num = 42;
fout << "Number: " << num << fendl;
long double pi = acosl(-1);
fout << "Pi: " << fsetprecision(20) << pi << fendl;Don't use fin and fout inconsistently with cin, cout, scanf() or printf() because it can be a cause of potential errors.
