Question

1. Input three decimal numbers in one line separated by spaces, and make sure to store them in different variables.
2. Multiply the 1st and 2nd decimal numbers, and store the product into a variable.
3. Then, divide the product of the 1st and 2nd decimal numbers with the 3rd decimal number, then print out its quotient, with 2 decimal places.

Input

A line containing three decimal numbers with two decimal places separated by a space.

1.53·2.25·1.23

Output

A line containing the result with two decimal places.

2.80

Answer 1

#include <iostream>
#include <iomanip>
using namespace std;
int main() {
	//Input three decimal numbers in one line separated by spaces, and make sure to store them in different variables.
	double number1;
	double number2;
	double number3;
	cin>>number1>>number2>>number3;
	//Multiply the 1st and 2nd decimal numbers, and store the product into a variable.
	double product=number1*number2;
	//Then, divide the product of the 1st and 2nd decimal numbers with the 3rd decimal number, 
	//then print out its quotient, with 2 decimal places.
	double quotient=product/number3;
	cout<<fixed<<setprecision(2)<<quotient<<"\n\n";
	system("pause");
	return 0;
