Problem G:array C time limit:1 Sec Memory limit:128 MB DescriptionGiving integers and and arrays and both with length, you should construct an array also with length which satisfied: 1.0≤Ci≤Ai(1≤i≤n)2.and make the value S is minimum.

The purpose and principle of an array with a length of 0 in struct, struct ArrayPreface In standard C and C ++, an array with a length of 0 is forbidden. However, in GNUC, there is a very strange usage, that is, an Array with a length of 0, such as

Regarding the output of the char pointer variable char * = p;, the pointer char I have always been confused when learning pointers. Please refer to the following code: # Include using std: cout; void main () {int num = 5; int * nPtr = & num; cout
