Re: Constant and pointer
your first program gives a warning because you r trying to store the address of const int variable into int type pointer.
here is the warning::" different 'const' qualifiers"
this is the reason you can change the value of const variable.if you create const type pointer variable then it gives an error : l-value specifier...
try this code..

void main()
    int const i=123;
    int *const ip;
    /* Changing constant integer i.e. const int/int const */
    printf(" %d %x \n",i,&i);
    printf(" %d %x %x %d \n",i,&i,ip,*ip);
