Pointers and Arrays

Arrays are special type of pointer.

When we declare an array, the name of array contains the address of array's first element.

#include <stdio.h>

void squares(int *a, int size)

{

int i;

for (i=0;i<size;i++)

{

*(a+i) = *(a+i) * *(a+i);

}

   

}

int main()

{

   int myarray[3] = {2,3,4};

   int i;

 //both statements will print same address value

  printf("myarray contains %u \n",myarray);

  printf("&myarray contains %u \n",&myarray);

  squares(myarray,3);

  for(i=0;i<3;i++)

   printf("%d   ", myarray[i]);

}
