Answer 1

You are not asking for input...

std::cout << "Please type if you want pickup or delivery: ";

after this line you need to get the user to input either pickup or delivery

ie

std::cin>>input;

next you need to swap getline(cin,address); and cin.ignore(); arround.. currently you are asking for input and then clearing the buffer.

also if (address == address) what are you trying to achieve here?

your code can be written like this

#include <iostream>

using namespace std;

int main()
{

    std::cout << "Please type if you want pickup or delivery: ";

    string input;
    string pickup;
    string delivery;
    string address;
     cin>>input;
    if (input == "pickup")
    {
        cout << "What pizza do you want(press r for a random pizza and c for cheese pizza!): ";
        cin >> input;
    }

    if (input == "delivery")
    {
        cout << "Tell me your adress and i will deliver a random pizza to ur house: ";
         cin.ignore();
        getline(cin,address);
        cout << "Thx we will delivery the pizza to " << address << " tommorow at 3PM!" << endl;
    }

 
    return 0;
}
