Exercice langage C fonctions passage des paramètres

Exercice 1

Implémentation:

#include <stdio.h>

main()
{
 void P(int X, int *Y); /* Prototype de la fonction appelée */ 
  int A,B;
 A=0;   
 B=0; 
 P(A, &B);
  printf("%d %d \n", A, B);
 return 0;
}

void P(int X, int *Y)
 {
 X = X+1;
 *Y = *Y+1;
 printf("%d %d \n", X, *Y);
}

Exercice 2

Implémentation:

#include <stdio.h>

main()
{
 void MACHIN(int X); /* Prototype de la fonction appelée */
 int A;
 A=2;   
 printf("%d \n", A);
 MACHIN(A);
 printf("%d \n", A);
 return 0;
}

void MACHIN(int X)
{
 printf("%d \n", X);
 X = 1000;
 printf("%d \n", X);
}

Exercice 3

Implémentation:

#include <stdio.h>

main()
{
 void MODIFIER(int X, int *Y, int *Z); /* Prototype */ 
  int A,B,C;
 A=3;   
 B=-8;
 C=12; 
 printf("%d %d %d \n", A, B, C);
 MODIFIER(A,&B,&C);
  printf("%d %d %d \n", A, B, C);
 return 0;
}
void MODIFIER(int X, int *Y, int *Z)
{
 int T;
 T  = X;
 X  = *Y;
 *Y = *Z;
 *Z = T;
}

Exercice 4

Implémentation:

#include <stdio.h>

main()
{
 void MANIPULER(int X, int Y, int *Z); /* Prototype */ 
  int A,B,C;
 A=208;   
 B=5;
 C=-34; 
 printf("%d %d %d \n", A, B, C);
 MANIPULER(A,B,&C);
  printf("%d %d %d \n", A, B, C);
 return 0;
}
void MANIPULER(int X, int Y, int *Z)
 {
 printf("%d %d %d \n", X, Y, *Z);
 X = X/2;
 Y = Y*2;
 *Z = X+Y;
 printf("%d %d %d \n", X, Y, *Z);
}
