Question

There is that way to set elements on array – int rgArrayNum [] = {16, 2, 77, 40, 12071};
How can I do same way on pointer with new ? I tried int *pArrayNum = new [] = {4 ,3 ,3} ; but it didn’t worked .

In c++11, you can write:

int *pArrayNum = new int[3]{4, 3, 3};

However, in c++03 array new initialization is not allowed; you’d have to initialize the members individually or by copy from an array on the stack:

int rgArrayNum [] = {16, 2, 77, 40, 12071};
int *pArrayNum = new int[sizeof rgArrayNum / sizeof rgArrayNum[0]];
std::copy(&rgArrayNum[0], &rgArrayNum[sizeof rgArrayNum / sizeof rgArrayNum[0]],
    pArrayNum);
