C ++将两个int数组连接成一个更大的数组 [英] C++ concatenate two int arrays into one larger array

问题描述

有没有办法在C ++中使用两个int数组

Is there a way to take two int arrays in C++

int * arr1;
int * arr2;
//pretend that in the lines below, we fill these two arrays with different
//int values

然后将它们组合成一个包含两个数组值的较大数组？

and then combine them into one larger array that contains both arrays' values?

推荐答案

int * result = new int[size1 + size2];
copy(arr1, arr1 + size1, result);
copy(arr2, arr2 + size2, result + size1);

只是建议， vector 会做得更好动态数组而不是指针

Just suggestion, vector will do better as a dynamic array rather than pointer
