using getline gives error: no matching function for call to ‘getline(std::istream&, const string&)’

I'm working on this code and it works with cin>>partname; instead of using getline(cin, partname); in the showpart function but for only names without blank space. But with using getline(cin, partname); it produces an error error: no matching function for call to ‘getline(std::istream&, const string&)’

#include<iostream>
#include<cstring>

using namespace std;

class Inventory
{
  private:
    int partno;
    string partname;
    float cost;
    void getpart()
    {
      cout<<"Enter the part number"<<endl;
      cin>>partno;
      cout<<"Enter the part name"<<endl;
      cin>>partname;
      cout<<"Enter the cost"<<endl;
      cin>>cost;
    }

  public:
    Inventory()
    {
      partno = 0;
      partname = " ";
      cost = 0.0;
    }

    Inventory(int pn,string pname,float c)
    {
      partno = pn;
      partname = pname;
      cost = c;
    }

    void setpart()
    {
      getpart();
    }

    void showpart() const
    {
      cout<<"Inventory details"<<endl;
      cout<<"Part Number: "<<partno<<endl;
      cout<<"Part Name: ";
      getline(cin, partname);
      cout<<"\nCost: "<<cost<<endl;
    }
};

int main()
{
  Inventory I1(1,"Resistor", 25.0), I2;
  I2.setpart();
  I1.showpart();
  I2.showpart();
}

I've looked through similar errors but they seem not to be helpful.Thank you for looking through this.

#include <string> instead of <cstring>.

Also: void showpart() const can't be const since you update partname (which is an odd activity for a function called show-something).

I suspect that you want to show the partname, not to update it:

void showpart() const
{
  cout<<"Inventory details"<<endl;
  cout<<"Part Number: "<<partno<<endl;
  cout<<"Part Name: "<<partname<<endl;
  cout<<"Cost: "<<cost<<endl;
}
