Most computer programming languages provide built-in standard sorting algorithms. Let’s compare performance of these. C++ Sorting The above graph shows performance of the standard C++ STL sort algorithm. The vertical axis is time measured in seconds. The horizontal axis is array size of integers (32-bits each). Signed 32-bit integer values in the array are random […]

Every programming language provides methods for generating random numbers, because random numbers are useful in so many situations. For years the C programming language only provided the rand() function, which generates 15 random bits per function call. To generate a 32-bit integer, it takes 3 calls to rand() to accumulate 32 bits. On my quad-core […]
