The encapsulation of the C ++ thread lock mainly provides operations such as lock, unlock, and require. Note that the thread repeatedly acquires the lock and sets a count counter, this calculator does not consider the atomic operations of ++ and --

++ I: Before using I, perform the auto-increment action; I ++. After I is used, the auto-increment action is performed. For example: (1) I = 1, j = I ++; // J = I ++, that is, J references the I value first, and then I completes the ++

The following is a question about constructor calling in C ++: is the output of the following code 0? # Include # Include Using namespace STD; Struct CLS { Int m_ I; CLS (int I): m_ I (I ){} CLS () { CLS (0 ); } }; Int main () { Cls
