Find cost price from given selling price and profit or loss percentage in C++

Consider we have the selling price, and percentage of profit or loss is given. We have to find the cost price of the product. The formula is like below −

$$Cost \: Price = \frac{Sell Price * 100}{100 + Percentage \: Profit}$$

$$Cost \: Price = \frac{Sell price *100}{100 + percentage\:loss}$$

Example

#include<iostream>
using namespace std;
float priceWhenProfit(int sellPrice, int profit) {
   return (sellPrice * 100.0) / (100 + profit);
}
float priceWhenLoss(int sellPrice, int loss) {
   return (sellPrice * 100.0) / (100 - loss);
}
int main() {
   int SP, profit, loss;
   SP = 1020;
   profit = 20;
   cout << "Cost Price When Profit: " << priceWhenProfit(SP, profit) << endl;
   SP = 900;
   loss = 10;
   cout << "Cost Price When loss: " << priceWhenLoss(SP, loss) << endl;
}

Output

Cost Price When Profit: 850
Cost Price When loss: 1000
