Note: The special trouble with enumeration at the beginning of enumeration is that it is directly enumerating the direction of the light, adding an enumeration of 0.01 from the entrance, especially when judging a particular position./************************************************************************* > File Name:poj_1039.cpp > Author:h

, which differs significantly from the other types.2. The difference between the top-level const and the underlying const when running copy operationsFor the top-level const and the underlying const, there is a distinct difference in running the object copy:(1) Top-level const is unaffectedint i = 0;const int ci =; Can not change the value of CI, this is a top level consti = CI; Correct: CI is a top-level const, no effect on this operation const int *P2 = ci; Agree to change the value of P2
Pointers can point to an ordinary type of data, such as int, double, char, or to a pointer type of data, such as int *, double *, char *, and so on.
If a pointer is pointing to another pointer, we call it a level two pointer, or a pointer to a pointer.
Suppose a variable a,p1 of type int is a pointer variable to a, P2 is a pointer variable that points to a P1, and their relationship is shown in the following illustration:
Convert this relationship to C language code:
int a =100;

mother and child string, filled with lowercase letters, p1=2, for the character string, filled with uppercase letters. In both cases, the number substring is populated in the same way. P1=3, whether it is a substring or a digital string, are populated with the same number of letters to fill the asterisk "*" to fill.(3) parameter P2: The number of repetitions of the fill character. P2=k indicates that the same character is to be continuously populated with K. For example, when p2=3, the substrin
