所以基本上我的代碼輸出是提示用戶每輛車的價格 ,然後保存輸入並使用以下代碼中的以下四個函數執行calcalcaltions。然後爲每輛車的display_total_Car_cost()
功能同時爲每輛車輸出以下內容。如何解決輸出問題?
我的問題是,我的代碼提示用戶兩次爲每個價格,然後顯示在同一時間所有汽車的以下輸出如何我更改我的代碼,以便它提示用戶爲每個汽車價格一次,然後輸出不同線路上每輛車的最後一個功能display_total_car_cost()
。下面是 是我的代碼,我將輸出註釋掉,這樣你就可以看到我的代碼正在輸出什麼。
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
#include <iomanip>
float get_vehicle_price(string);
float calculate_other_costs(float);
float calculate_registration_fee(float);
void display_total_car_cost(string, float, float);
int main() {
ifstream myfile;
string car;
string car2;
string car3;
string car4;
myfile.open("infile.txt");
getline(myfile, car);
getline(myfile, car2);

string model1 = car;

string model3 = car3;
string model4 = car4;
display_total_car_cost(model1, price1, other_costs1);
display_total_car_cost(model2, price2, other_costs2);
display_total_car_cost(model3, price3, other_costs3);
display_total_car_cost(model3, price4, other_costs4);
return 0;
}
float get_vehicle_price(string carname) {

cout << "Enter the price of the :" << carname;

return carprice;
}
float calculate_other_costs(float price) {
float salestax = price *0.06;
float other_costs = salestax + calculate_registration_fee(price);
return other_costs;
}
float calculate_registration_fee(float price) {
const int administrative_fee = 240;
const int cost_of_tags = 120;
float registration_fee = (price *0.10) + administrative_fee + cost_of_tags;
return registration_fee;
}
void display_total_car_cost(string models, float price, float other_cost){
float totalcost = price + other_cost;
cout << fixed << showpoint << models << setw(2) << setprecision(2) << price << setw(3) << setprecision(4) << other_cost << setw(4) << setprecision(2) << totalcost;
}
如果你創建一個[MCVE]你就會有更多的成功在這裏。 –
而不是'string model1','string model2'等...考慮使用一個數組:'string model [4];' – user4581301
