Int I =-1;Bool B = int. tryparse (null, out I );After the execution is complete, B is equal to false, I is equal to 0, rather than-1. Remember. Int I =-1;Bool B = int. tryparse ("123", out I ); After the execution is completed, B is equal to true,

The int* representation is an int pointer; (*a[5]) (int, char*) a[5] means an array with 5 elements, while (*) (int, char*) represents a pointer to a function that has two arguments, the first argument is an int type, The second is the character

The following is a detailed analysis of the use of int (*p) [] and int (**p) [], and the need for friends can refer to the following 1. Int (*p) [10]: Depending on the binding law of the operator, () has the highest precedence, so p is a pointer to

The following describes the use of int (* p) [] and int (** p) [] in detail. For more information, see 1. int (* p) [10]:According to the Union law of operators, () has the highest priority. Therefore, p is a pointer pointing to a one-dimensional

Fix (number) and Int (numbers) are integral parts of the returned digits. When number is positive, the two return the same value. For example: Fix (3.6) =3,int (3.6) = 3. When number is negative, Fix removes the decimal part directly, and INT

Note: M here is not a specific length stored in the database, it was always mistaken for int (3) to store only 3-length numbers, and int (11) would store 11-length numbers, which is a big mistake.In fact, when we choose the type of int, whether it
