The objective of this support is to make the students learn how to solve a problem. We have introduced in TD1 all the data structures that will be the objects of manipulation of all the control definitions that will follow. As for the control structures, we have developed them separately in two tutorials (TD2 and TD3). We will start with exercises on simple structures, then conditional structures and finally iterative structures. These three tutorials will allow us to manipulate strings which will be our TD4. We will treat in this tutorial the programs generally asked so that the student will be able to solve problems which resemble them. These tools will allow us later to approach functions and procedures in TD5. Indeed, subprograms are the basis of programming to simplify the writing of a program and make it more readable. After TD6, which will be devoted to arrays and advanced processing, we will see in the latter the search algorithms and sorting algorithms. Then, TD7 which is dedicated to the manipulation of complex types
