C Programming Language¶

Learning C¶

The best way to learn programming is, always, writing your own code!
Why Code in C Anymore?….Instead of C++
- C still has a little advantage on the performance and portability.

Optimization of Computer Programs in C
- By Michael Lee. “It focuses on minimizing time spent by the CPU and gives sample source code transformations that often yield improvements. Memory and I/O speed improvements are also discussed.”
Tips for Optimizing C/C++ Code
- Very practical and useful guides for optimizing C/C++.
mimalloc - mimalloc is a compact general purpose allocator with excellent performance
- By Microsoft. mimalloc (pronounced “me-malloc”) is a general purpose allocator with excellent performance characteristics. It is a drop-in replacement for malloc and can be used in other programs without code changes.

GSL - GNU Scientific Library
- The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite.

FFTW
- FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).
