问题描述
I've got a method that receives a variable int. That variable constitutes an array size (please, don't offer me a vector). Thus, I need to init a const int inside my method to initialize an array of specific size. Question: how do I do that?
void foo(int variable_int){
int a[variable_int] = {0}; //error
}
解决方案
int *a = new int[variable_int];
Remember to delete[] the allocated space when you are done with it!
