# TP 1 : Mémoire # TP 1 : Mémoire
## Exercice 1 ## Exercice 1
Soit le [programme](Exo1/adresses_virtuelles.c) suivant qui affiche les adresses virtuelles de certaines variables lors de l'exécution du processus.
En utilisant le (pseudo) fichier `/proc/pid/maps`, vérifiez à quel segment de pages ces adresses appartiennent.
```console
tom@Error404:/mnt/c/Users/naser/Documents/scr/TP1$ ./adresses_virtuelles
```
>mon pid est 20
```
main = 0x564bfc70e169
&argc = 0x7ffd8f4ac78c
&i = 0x7ffd8f4ac794
&j = 0x564bfc711fe0
t = 0x564bfc711040
m = 0x564bfd7e62a0
```
```console
tom@Error404:/mnt/c/Users/naser/Documents/scr/TP1$ cat /proc/20/maps
```
```
