constant n

Objective: In peacetime we use the string is generally used to get directly, very little in-depth to think about this knowledge , leading to others in the examination of our time, will ask the string str = new String ("123"); This line of code

In C/C ++ learning, some people often cannot understand the concepts of "constant Pointer" and "pointer constant. In fact, the data on the address pointed to by the "constant Pointer" is a constant, while the address pointed to by the "pointer

ObjectiveA few days ago the woman ticket asked me a Ali's face question, is about the C + + language const constant, in fact, she mentioned that I know the point of inspection: it is certain that the const constant memory is not allocated in the

Java memory allocation: 1. Register: we cannot control it in the program2. STACK: stores basic data and object references, but the object itself is not stored in the stack, but stored in the heap.3. Heap: store data generated with new4. static

First, post a document Int p; // This is a common integer variable int * p; // It starts from P and is first combined with *, so P is a pointer and then combined with int, indicates that the Pointer Points to the int type of content. so P is a
