Recursive problem-solving approaches have a number of elements in commmon. A recursive function is called to solve a problem. The function actually knows how to solve only the simplest case. If the function is called with a base case, the function simply returns a result. If the function is called with a more complex problem, the function divides divides the problem into two comceptual pieces- a piece that the function knows how to do and a piece that the function doesn’t know how to do. To make recursion feasible, the latter piece must resemble the original problem, but be a sightly simpler or smaller version of the original problem. The recursion step often includes the keyword return, because its result will be combined with the portion of the problem the function knew how to solve to form a result.

An example of recursion is the Fibonacci serie shown in the picture.

The for repetition structure handles all the details of counter-controlled repetition. The picture shows an example.

The general format of the for structure is

for ( initialization statement; loop continuation condition; increment )

When the for structure begins executing, the control variable i is declared and inicialized to 0. Then, the loop-continuation i <= size is checked. The inicial value of i is 0, so the condition is satisfied and the body statement prints the value of i, namely 0. Then the expresion i++  increments control variable i and the loop begins again with the loop-continuation test. The control variable is now equal to 1, so the final value is not exceeded and the program performs the body statement again. This process continues until the control variable i is incremented upper than the value size given by the user- this causes the loop-continuation test to fail and repetition to terminate. The program continues by performing the first statement after the for structure.

Creating C++ functions

In C++, a function is a group of statements that is given a name, and which can be called from some point of the program. You need a type of the value returned by the function,  a identifier by which the function can be called, and parameters. Each parameter consists of a type followed by an identifier, with each parameter being separated from the next by a comma. Each parameter looks very much like a regular variable declaration and in fact acts within the function as a regular variable which is local to the function. The purpose of parameters is to allow passing arguments to the function from the location where it is called from.

This is one example I did for WSQ08
