Additional Exercises on Simple Sequential Algorithms

This series offers a set of supplementary exercises for individual work on simple sequential algorithms. The solutions to these exercises are available on the module's Facebook page. It's important to note that these exercises are a supplement and by no means replace the classes and educational resources provided in the classroom. They are designed to enhance your understanding and provide additional opportunities for practice and self-learning.

1. Exercice 5:

Ecrire un algorithme/programme qui calcule la somme de quatre nombres entiers entrés au clavier, en se servant de 2 variables uniquement.

Solution :

Algorithme:

Algorithm calcul;

Var n,s:Integer;

Begin

Write("Donner le premier nombre: ");

Read(n);

s ← n;

Write("Donner le deuxième nombre: ");

Read(n);

s ← s+n;

Write("Donner le troisième nombre: ");

Read(n);

s ← s+n;

Write("Donner le quatrième nombre: ");

Read(n);

s ← s+n;

Write("La somme est: ",s);

End.

Programme C:

#include <stdio.h>

#include <stdlib.h>

int main(){

int n,s;

printf("Donner le premier nombre: ");

scanf("%d",&n);

s=n;

printf("Donner le deuxieme nombre: ");

scanf("%d",&n);

s=s+n;

printf("Donner le troisieme nombre: ");

scanf("%d",&n);

s=s+n;

printf("Donner le quatrieme nombre: ");

scanf("%d",&n);

s=s+n;

printf("La somme est: %d",s);

return 0;

}
