C + + memset

Assigning an initial value to an array of pointers:

#include <iostream> #include <cstring>using namespace Std;int main () {int *p = new Int[5];    memset (p,0,5*sizeof (int));    for (int i = 0; i < 5; i + +) {cout << * (P + i) << Endl;    } delete[] P; return 0;}

Memset: Can be understood as Memory Set

First parameter: The address of the array

Second parameter: initial value

Third parameter: Total number of bytes

It is important to note that if you assign a value type to the initial values it can only be 0 or-1

Also need to introduce: CString

To release the array pointer: delete[] P--needs to be added after the delete []
