第27行：在＆amp;之前的预期主要表达代币

Question

我正在尝试创建一个地址簿，但我不断收到“expected primary expression before '&' token” 我还希望能够编辑和创建多个地址条目！

#include <iostream>
#include <string>
using namespace std;

struct addressinfo
{
    string Name;
    string Address;
    string Phonenumber;
};
addressinfo info;

addressinfo gna(addressinfo& info) {// get new address
    addressinfo accessinfo;
    info.Name;
    info.Address;
    info.Phonenumber;
    return accessinfo;
}

void address_menu() {
    int choice;
    cin >> choice;
    switch(choice) {
    case 1:
        addressinfo info = gna(addressinfo& info);
        break;
    }
}

int main() {
    cout << "Hello world!" << endl;
}

Answer 1

addressinfo info = gna(addressinfo& info)应为addressinfo info = gna(info)，因为您正在调用一个函数，而不是创建函数。
