Normal: The previous database operation will be executed, and all data save operations that occur after the database operation error and subsequent failures will fail. This should not be the result we want.The runtime will download the mirrored

The reason for the exposure to this concept is that there is this piece of code:#include void main () { int55, p, q; = (i++) + (i++) + (i++); = (++j) + (++J) + (+ +j); printf ("%d,%d\n", p, q);}This code, compiled in vc++6.0 and

1: As long as the pointer type, regardless of the number of pointers "with a few *", its width is 4 bytes2: Any data type "including its own defined structure" can be preceded by an * number, indicating a pointer to the data type3: Because it is a 38

Today, the written test encountered a problem, then wrote before the function is declared as C, compiled by C.The first is to call C + + functions, including normal functions, overloaded functions, and member functions.For normal functions, declared
