使用

int* salary_pointer = new int[20];

相反，当您分配20个int时，不只是一个.然后，使用

instead, as you allocate 20 ints, not just one. Then, delete the dynamic array using

delete[] salary_pointer;

而不是delete salary_pointer.这里也要小心:

instead of delete salary_pointer. Be also careful here:

salary[i] / (i + 1);

如果操作数为int，则最终会被截断.如果希望结果作为double，请使用salary[i]/(i + 1.)(在这种情况下，***将salary做成double的数组或指向double的指针，这样就不再有此问题了).

If the operands are int, then you end up with truncation. Use salary[i]/(i + 1.) in case you want your result as a double (in which case you better make salary an array of doubles or a pointer to double so you don't have this issue anymore).
