C :

#include<stdio.h>
void main()
{
	int z,i,m,n,s;
	scanf("%d%d%d",&m,&n,&s);
	i=s/n;
	z=m*i;
	printf("%d\n",z);
 }  

C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){

	int n,m,s,b;
	cin>>n>>m>>s;
	b=s/m;
	cout<<n*b<<endl;


	return 0;
}

Pascal :

program ex_1;
var
  a,b,c:longint;
begin
  read(a,b,c);
  write(c div b*a);
end.  

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		//获取整数m、n、s
		int m = sc.nextInt();
		int n = sc.nextInt();
		int s = sc.nextInt();
		int i ;
		i = (s / n)*m;
		System.out.print(i);
	}
}

Python :

m,n,s=map(int,input().split())
a=s/n #求得花圃原宽
b=m*a #求得花圃原面积
print('%.f'% b)
