查找折扣率的程序

给定标价$M$和售价为$S$产品。任务是计算应用于该产品的折扣百分比。

例子：

Input: M = 120, S = 100
Output: 16.66%

Input: M = 1000, S = 500
Output: 50%

计算产品折扣率的数学公式为：

Discount = Marked Price - Selling price

Therefore,
Discount Percentage = (Discount / Marked Price) * 100

以下是查找产品折扣百分比的程序：

C++

// CPP Program to find the Discount Percentage
  
#include 
using namespace std;
  
// Function to find the Discount Percentage
float discountPercentage(float S, float M)
{
    // Calculating discount
    float discount = M - S;
  
    // Calculating discount percentage
    float disPercent = (discount / M) * 100;
  
    return disPercent;
}
  
// Driver code
int main()
{
    int M, S;
    M = 120;
    S = 100;
      
    // Setting the precision to 2 decimals
    cout << std::fixed << std::setprecision(2)
        << discountPercentage(S, M) << "%" << endl;
  
    M = 1000;
    S = 500;
      
    // Setting the precision to 2 decimals
    cout << std::fixed << std::setprecision(2)
        << discountPercentage(S, M) << "%" << endl;
  
    return 0;
}

Java

// Java Program to find the Discount Percentage
  
import java.util.*;

import java.io.*;
  
class GFG{
   
// Function to find the Discount Percentage
static float discountPercentage(float S, float M)
{
    // Calculating discount
    float discount = M - S;
   
    // Calculating discount percentage
    float disPercent = (discount / M) * 100;
   
    return disPercent;
}
   
// Driver code
public static void main(String args[])
{
    int M, S;
    M = 120;
    S = 100;
  
    System.out.printf("%.2f",discountPercentage(S,M));
    System.out.println("%");
      
   
    M = 1000;
    S = 500;
  
   System.out.printf("%.2f",discountPercentage(S,M));
    System.out.println("%");
}
}
