Explain the term relocation. Explain the structure of Typical ELF executable object file. 

What would be the output on the terminal when a user tries to compile and execute the following files. Write the steps to compile and run as well. 

#include <stdio.h>

int buf[]={1,3};

int main()

{

  swap();

printf("x= %d , y=%d\n", buf[0], buf[1]);

  return 0;

}

 

#include <stdio.h>

extern int buf[];

 

int *bufp0 = &buf[0];

static int *bufp1;

void swap()

{

  int temp;

  bufp1 = &buf[1];

  temp = *bufp0;

  *bufp0 = *bufp1;

  *bufp1 = temp;

}
