"Compiling principle" lesson notes 2

The following are mainly notes for experiment Two and experiment three:

April 13, 2015 P111.arr,&arr (arr+1), (&arr+1) difference: One variable corresponds to a memory eg. address: 0x10000->&arr content:0x20000-> Arr array is exception: 1) array name arr->&arr[0]  arr[0]->int (first address of array)  INT * *) typedef int Array[10]array a;//sizeof (a)- >40&arr->array*sizeof (arr);->403) so: arr//10000 (arr+1)//10004 (&arr+1)//100402.p395 source code C language Conventions, Right-to-left "argument elevation" int printf (char *fmt,...) {usigned int addr = (usigned int) (&FMT), addr + = sizeof (char*),//1004double *prt = (double*) addr;*prtdouble h = * ((Doub Le *) addr); addr + = sizeof (double);} 3. Experiment two variable argumentva_arg ptr//1iptr//4 do int myprintf (const char,...) {*format}
