Cant access public function? no member named?

I am trying to access the function getnoOfkids() but even though its public I can't, why? I am only able to access the normal queue operations such as size,emplace, etc..

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

class Family
{
private:
    int id, noOfElders, noOfKids;
public:
    bool operator ==(const  Family &f)
    {
        if ((this->id!= f.id) || (this->noOfElders != f.noOfElders)||(this->noOfKids != f.noOfKids))
        {
            return false;
        }
        return true;
    }

    bool operator !=(const  Family &f)
    {
        return !(*this==f); //////////////////////
    }

    Family(int ide=0, int eld=0, int kid=0) {
        noOfElders = eld;
        noOfKids = kid;
        id = ide;
    }

    Family(const Family &a) {
        noOfKids = a.noOfKids;
        noOfElders = a.noOfElders;
        id = a.id;
    }

    Family operator=(Family const &a) {
        this->id = a.id;
        this->noOfElders = a.noOfElders;
        this->noOfKids = a.noOfKids;
        return *this;
    }

    int getnoOfkids() const  {
        return noOfKids;
    }

    int getnoOfElders() const {
        return noOfElders;
    }

    int getid() const {
        return id;
    }

    void setnoOfKids(int x) {
        noOfKids = x;
    }

    void setnoOfElders(int x) {
        noOfElders = x;
    }

    void setid(int x) {
        id = x;
    }

    friend ostream & operator<<(ostream & out, const Family & a)
    {
        out << "The id of the travelers are: " << a.id << endl;
        out << "The number of elders are: " << a.noOfElders << endl;
        out << "The number of kids are: " << a.noOfKids << endl;
        return out;
    }

    friend istream &operator >> (istream &in, Family &a) {
        in >> a.id;
        in >> a.noOfElders;
        in >> a.noOfKids;
        return in;
    }
};

queue<Family> KidsQueue(queue<Family> &a, queue<Family> &b) {
    queue <Family> newA,newB;
    queue <Family> result;

    queue <Family> newA,newB; queue <Family> result;
    while(!a.empty()) 
    { if(a.getnoOfElders()) }
}

In KidsQueue(), your a parameter is an instance of std::queue holding elements of type Family. a itself is not a Family, so you can't call Family methods on it. You need to access individual Family objects inside of the queue to call Family methods on them, eg:

while (!a.empty()) 
{
    if (a.front().getnoOfElders()) // <-- front() accesses the 1st Family object in the queue
    {
        ...
    }
    a.pop();
}
