下面C++程序的输出是_________。
#include <iostream>
int f(int &a, int &b) {
a = 9;
b = 5; return a + b;
}
int main() {
int a = 2;
int b = 7;
int c = f(a, a);
std::cout << a << b << c;
}
int f(int &a, int &b) {
a = 9;
b = 5; return a + b;
}
int main() {
int a = 2;
int b = 7;
int c = f(a, a);
std::cout << a << b << c;
}
