从函数中获取多个值

Question

可能重复:
从C++函数返回多个值

/************************************************/
/* Name: premserv                               */
/* Description: Calculations for premium serv   */
/* Parameters: N/A                              */
/* Return Value: premserv                       */
/************************************************/

float premserv ()
{
  int daymin = 0;         //Var for day minutes
  int nightmin = 0;       //Var for night minutes
  float daytotal = 0;     //Var for day total
  float nighttotal = 0;   //Var for night total
  float premserv = 0;     //Var for premium service cost

  cout << "\n" << "Please enter the number of minutes used durring the day (6AM - 6PM): " << "\n";
  cin >> daymin;
  cout << "\n" << "Please enter the number of minutes used durring the night (6PM - 6AM): " << "\n";
  cin >> nightmin;

  daytotal = (daymin - 75) * 0.1;
  nighttotal = (nightmin - 100) * 0.05;
  premserv = 25 + daytotal + nighttotal;

  return premserv;

}

我需要从函数中获取daymin,nightmin和premserv的值.我只知道如何从函数中获取1个值.

Answer 1

创建一个包含所有三个浮点数的结构,并返回该结构而不是单个浮点数.
