What I have tried:

I try too change the { at the beginning and at the end but the program still not work help me please thanks you.

Look at your code:

C

#include <stdio.h>
#include <stdlib.h>
#include <math.h>


typedef int vect [30];

//Prototypes*//
void aff_tableaux (vect LOL, int n); //void car elle ne retourne rien
int somme (vect LOL, int n);
float ecart_type (vect LOL, int n);
float val_minimale (vect LOL, int n);
float val_maximale (vect LOL, int n);

//***************************************************************************//

//fonctions//

void aff_tableaux (vect LOL, int n);
{
{     
    int i;

You have a function prototype for aff_tableaux then you follow it with a second prototype for the same function, and two odd looking open curly brackets.
Probably, you didn't want one of the open curlies, and you don't want the semicolon:

C

void aff_tableaux (vect LOL, int n)
{     
    int i;

That should start to get rid of your errors - but do look closely at your code when you get syntax errors, as it's a lot quicker to fix them yourself than wait for others to do it for you! :laugh:

Solution 2

on top of what 'Griff said, you also have a semicolon where it doesn't belong. It needs to be removed:

C

int main (void);

I tried to fix the (numerous) bugs of your code. The result is below.

C

#include <stdio.h>
#include <stdlib.h>
#include <math.h>


typedef int vect [30];

//Prototypes*//
void aff_tableaux (vect LOL, int n); //void car elle ne retourne rien
int somme (vect LOL, int n);
double moyenne (vect LOL, int n);
void ecart_type (vect LOL, int n);
int valeur_minimale (vect LOL, int n);
int valeur_maximale (vect LOL, int n);

//***************************************************************************//


int main ()
{
  int N, i;
  vect B;

  do
  {
    printf("Veuillez entrez le nombre d'entiers N a saisir: \n");
    scanf("%d", &N);
    printf ("N = %d \n", N);
  } while (N>30); // Si l'utilisateur demande plus de 30 valeurs, recommencer la saisie


  for (i = 0; i<N; i++)
  {
    printf("Saisissez les valeurs a entrer dans le tableau\n");
    scanf("%d", &B[i]);
  }

  aff_tableaux(B,N);
  printf("Somme s = %d \n", somme(B, N));
  printf ("Moyenne m =%f \n", moyenne(B, N));
  ecart_type(B, N);
  printf ("La valeur minimale est de =%d \n", valeur_minimale(B, N));
  printf ("La valeur maximale est de =%d \n", valeur_maximale(B, N));

  return 0;

}

//fonctions//

void aff_tableaux (vect LOL, int n)
{
  int i;

  printf("Les elements du tableaux sont:\n");
  for (i =0; i<n; i++)
    printf("%d\n", LOL[i]);

}

int somme(vect LOL, int n)
{
  int i;
  int s = 0;
  for (i = 0; i<n; i++)
  {
    s = s + LOL[i];
  }

  return s;
}

double moyenne (vect LOL, int n)
{
  double m = somme(LOL, n)/((double)n);

  return m;
}

void ecart_type (vect LOL, int n)
{
  int i;
  double m = moyenne(LOL, n);

  for (i = 0; i<n; ++i)
  {
    double e_t = m - LOL[i];
    if (e_t < 0) e_t = -e_t;
    printf ("Ecart-type e_t[%d] =%f \n", i, e_t);
  }

}

int valeur_minimale (vect LOL, int n)
{
  int val_min = LOL[0]; // TODO: handle the n==0 corner-case
  int i;

  for (i=1; i<n; i++)
  {
    if( LOL[i] < val_min)
    {
      val_min = LOL[i];
    }
  }
  return val_min;
}

int valeur_maximale (vect LOL, int n)
{
   int val_max = LOL[0]; // TODO: handle the n==0 corner-case
   int i;

   for (i=0; i<n; i++)
   {
     if(LOL[i]>val_max)
     {
       val_max = LOL[i];
     }
  }
  return val_max;
}
