Pointers to C language pointers arrays and struct bodies

A pointer to an array that initializes an array, using the traditional way of traversing

1 voidMain ()2 {3     inta[5] = {1,2,3,4,5 };4      for(inti =0; I <5; i++)5     {6printf"%d,%x\n", A[i], &a[i]);7printf"%d,%x\n", * (a+i), a+i);//equivalent a[i], &a[i]8     }9}

A is the first address of the array A, that is, the address of element 1, a + 1 for address +1, that is, to increase the length of int 4 bytes, point to the address of the next address is element 2

1 int a[51,2,3,4,5  }; 2 int // Create a null pointer 3 p = A; // p is a pointer variable and a is the address    of the array's first ADDRESS element 1

Because we use the pointer traversal to achieve the same effect.

1 // using the pointer loop 2  for (int *pp = A; pp<a+5; pp++)  // address + + 3 {4     printf ("%d,%x\n", *pp, pp); 5 }

With the above understanding, the pointer structure is actually the same.

1 //pointer structure Body2 structInfo3 {4     Charname[ -];5     intID;6 };7 8 voidMain ()9 {Ten     structInfo myinfo[5] = { {"ZC1",1},{"ZC2",2}, {"ZC3",3}, {"ZC3",3}, {"ZC4",4} }; One      A     //Normal Mode output -      for(inti =0; I <5; i++) -     { theprintf"%s,%d\n", Myinfo[i].name, myinfo[i].id); -         //Pointers -printf"%s,%d\n", (* (Myinfo+i)). Name, (* (MyInfo +i)). ID); -     } +  -     //using the pointer loop +     structInfo *px =MyInfo; A      for(; px < MyInfo; px++) at     { -printf"%s,%d\n", Px->name, Px->id);//pointer structure output mode pointer variable-Properties -printf"%s,%d\n", (*PX). Name, (*PX). ID);//pointer structure output mode * pointer variable. Properties -         //px->id equivalent (*PX). ID -     } -  in GetChar (); -  to}
