Analysis and code :[ author : Lu changheel ]:

analysis ：

There should be nothing to analyze , At most, pay attention to the data type of the input number , And the implementation method of keeping decimals

Code ：

#include <iomanip>

#include <iostream>

using namespace std;

int main()

{

       double qz;

       double sw;

       cin>>qz>>sw;

       double swl=(sw/qz)*100;

       cout<<setprecision(3)<<swl;
