复制代码 代码如下:

#include <iostream>

#include <initializer_list>

using namespace std;

int get_sum(int, initializer_list<int>);

int main(int argc, char *argv[])

{

cout << get_sum(2, {1,2,3}) << endl;

return 0;

}

int get_sum(int i, initializer_list<int> il) {

int sum = 0;

sum += i;

for (auto a : il) {

sum += a;

}

return sum;

}
