+## Allocation mémoire
+
+### Allocation statique
+
+On peut allouer de la mémoire statiquement à deux endroits :
+
+- dans le segment `.data` lors d'une initialisation explicite,
+- dans le segment `.bss` lors d'une initialisation par zéro.
+
+<!-- $MDX file=memory_layout.c -->
+```c
+// memory_layout.c
+
+#include <stdio.h>
+#include <stdlib.h>
+
+const int x = 3;
+
+int y = 5;
+
+static int i;
+
+char *my_str = "this should appear in .data";
+
+int main(void) {
+
+  printf("x = %d\n", x);
+
+  printf("y = %d\n", y);
+  y = 10;
+  printf("y = %d\n", y);
+
+  printf("i = %d\n", i);
+  i = 42;
+  printf("i = %d\n", i);
+
+  exit(0);
+}
+```
+
+```sh
+$ gcc memory_layout.c -o memory_layout.exe
+$ size ./memory_layout.exe
+   text	   data	    bss	    dec	    hex	filename
+   1790	    608	      8	   2406	    966	./memory_layout.exe
+```
+
+### MDX test
+
+```ocaml
+# 1 + 2;;
+- : int = 3
+```
