Why does this bit of code, const float x[16] = { 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1,

Create a function, compose, whose two arguments f and g, are both functions with one argument. The result of compose is to be a function of one argume
Continue ReadingC++: Closest-Pair Problem
The aim of this task is to provide a function to find the closest two points among a set of given points in two dimensions, i.e. to solve the Closest

The task is to demonstrate the language's ability to include source code from other files. In C and C++, inclusion of other files is achieved via a
Continue ReadingC++: Multiple Distinct Objects
Create a sequence (array, list, whatever) consisting of n distinct, initialized items of the same type. n should be determined at runtime. By disti
Continue ReadingC++: Anonymous Recursion
While implementing a recursive function, it often happens that we must resort to a separate "helper function" to handle the actual recursion. This
Continue ReadingC++: Compile-Time Calculation
Some programming languages allow calculation of values at compile time. For this task, calculate 10! at compile time. Print the result when the progra

In this task, the job is to verify that a file called "input.txt" and the directory called "docs" exist. This should be done twice: once for the curre
