Question

我正在尝试将用户输入的名称插入到预先存在的字符串中，并且我不断收到错误消息：

“[错误]没有匹配函数来调用'std :: basic_string :: insert（std :: basic_string :: iterator，std :: string＆amp;）'” 第25行

代码：

#include <iostream>
#include <string>

using namespace std;
string custName = " ";
string firstName = " ";
string midInitial = " ";
string lastName = " ";
string getFullName = "";
string comma = ",";

int getName()
{
    cout<<"Please enter your first name \n";
    cin>>firstName;
    cout<<"Please enter your middle initial \n";
    cin>>midInitial;
    cout<<"Please enter your surname \n";
    cin>>lastName;

    getFullName = firstName+" "+midInitial+". "+lastName;
}

int addName()
{
    custName.insert (custName.end(), ',');
    custName.insert(custName.end(), getFullName);
}

int main ()
{
    getName();
    custName = getFullName;
    getName();
    addName();
    getName();
    addName();
    getName();
    addName();
    cout<<custName
}

std::string::insert 没有功能签名，如：

basic_string& insert( iterator pos, const basic_string& str );

更新

custName.insert(custName.end(), getFullName);

为：

custName.insert(custName.end(), getFullName.begin(), getFullName.end());

或

custName.insert(distance(custName.end(), custName.begin()), getFullName);

不太了解插入功能，得到一个我似乎无法通过的错误
