C :

#include<stdio.h>
int main()
{
	int a;
	scanf("%d",&a);
	printf("%d\n%.1f",a/100+a%100,(a/100)*1.0/(a%100));
	return 0;
}

C++ :

#include <iostream>
#include <iomanip>
using namespace std;

int main(){
	int n,g,s,b,q;
	cin>>n;
	q = n / 1000;
	b = n / 100 % 10;
	s = n / 10 % 10;
	g = n % 10;
	cout<<q*10+b+s*10+g<<endl;
	cout<<fixed<<setprecision(1)<<(q*10+b)*1.0/(s*10+g);
}

Java :

import java.util.Scanner;

public class Main {
	 
    /**
     * @param args
     */
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int g = a%10;
		int s = a/10 %10;
		int b = a/100 %10;
		int q = a/1000;
		int x = b + q*10;
		int y = g + s*10;
		System.out.println(x+y);
		System.out.println(String.format("%.1f", (double)x/y));
	}
	public static void printArr(int [] a){
		for (int i = 0 ;i<= a.length - 1 ;i++) {
			System.out.print( a[i] + " ");
		}
	}
}

Python :

n = int(input())
q = n // 1000 % 10
b = n // 100 % 10
s = n // 10 % 10
g = n // 1 % 10
x = q * 10 + b
y = s * 10 + g
print(x + y)
print("%.1f" % (x / y))
