Evaluation of C Library Function rand() and the Associated Compilers Available Off the Shelf for Windows 10 and Kubuntu 19.04

Abstract

This paper documents the observations made with respect to library function rand() on Windows 10 and Kubuntu 19.04 platform with various compilers such as TDM-GCC 4.9.2 64 bit for Windows 10, clang for Windows 10,Microsoft Visual Studio VC++ compiler for Windows 10 and gcc for Kubuntu 19.04 for a very simple C program. The observations were with respect to uniqueness of the generated random numbers and execution speed of the whole program.
