c_cpp 使用在堆栈上声明的数组（int myArray [3]）和堆上的数组（int * myArray = new int [size]

Posted 2021-05-14

int myArray[3] = {1,2,3}; //on the stack
int *myPrray = new int[3];
myPrray[0] = 1;
myPrray[1] = 2;
myPrray[2] = 3;

cout << myArray[2] << " " << *(myPrray+2) << endl;  ///pointer arthimetic

int *test = new int[2];
(*test) = 99;
*(test+1) = 100;
cout << *test << " " << *(test+1) << endl;
