Using the following table, write a program that reads a code and the amount of an item. After, print the value to pay. This is a very simple program with the only intention of practice of selection commands.

Input

The input file contains two integer numbers X and Y. X is the product code and Y is the quantity of this item according to the above table.

Output

The output must be a message "Total: R$ " followed by the total value to be paid, with 2 digits after the decimal point.

Input Sample	Output Sample
3 2	Total: R$ 10.00

4 3	Total: R$ 6.00

2 3	Total: R$ 13.50

Solution:

• [tab]
• C

• #include<stdio.h>
  int main()
  {
      int X, Y;
      float price = 0;
  
      scanf("%d %d", &X, &Y);
      if (X == 1)
      {
          price  = (float) (4.00 * Y);
      }
      else if (X == 2)
      {
          price  = (float) (4.50 * Y);
      }
      else if (X == 3)
      {
          price  = (float) (5.00 * Y);
      }
      else if (X == 4)
      {
          price  = (float) (2.00 * Y);
      }
      else if (X == 5)
      {
          price  = (float) (1.50 * Y);
      }
  
      printf("Total: R$ %.2f\n",price);
  
  }

• C++

• #include <iostream>
  #include <iomanip>
  
  using namespace std;
  
  int main()
  {
   int t;
   float q;
  
   cin >> t >> q;
  
   if(t == 1){
    q *= 4.0; 
   }else if(t == 2){
    q *= 4.5;
   }else if(t == 3){
    q *= 5.0;
   }else if(t == 4){
    q *= 2.0;
   }else{
    q *= 1.5;
   }
  
   cout << "Total: R$ " << setprecision(2) <<  fixed << q << endl;
  
   return 0;
  }
