运行下面的代码，屏幕上将输出（ ）。
#include <iostream>
using namespace std;
int divide(int a, int b) {
if (b == 0) {
throw runtime_error("division by zero error ");
}
return a / b;
}
int main() {
int x = 10;
int y = 0; // 设为 0 会导致除零错误
try {
int result = divide(x, y);
cout << "result: " << result <<endl;
}catch (const runtime_error& e) {
cout << "caught an exception: " << e.what() << endl;
}
return 0;
}
- A.
division by zero error result: caught an exception: - B.
result: caught an exception: division by zero error - C.
caught an exception: division by zero error - D.
division by zero error caught an exception: division by zero error
