calling a class function in main but it's declared in it's own cpp

[Pdsnowden]

in my class.h i have.

  class AddressBook
{
private:
	string firstName;
	string lastName;
	int streetNum;
	string streetName;
	string city;
	string state;
	int zipCode;

public:
	void setFirstName(string temp);
	void setLastName(string temp);
	void setStreetNum(int tempInt);
	void setStreetName(string temp);
	void setCity(string buff);
	void setState(string buff);
	void setZipCode(int zip);

and in the class.cpp i have

void AddressBook::setFirstName(string temp) {

	AddrBook[entryCnt].firstName = temp;

	cout << AddrBook[entryCnt].firstName;
	
}

and in main.cpp i have

setFirstName(temp);

but yet visual studios is flagging the function in main saying "setFirstName identifier not found".


any help would be greatly appreciated.

setFirstName(temp);

You need an object to call the function., like:

AddressBook addresses;

addresses.setFirstName("name");
