I want to submit the solution in C language. What language I should choose from the option and what is the error in following coding:-
#include <stdio.h>

int main()
{
    double a,b;
    scanf("%lf %lf",&a,&b);
    printf("%lf",a+b);
    return 0;
}

As you can see, it was well written, but when it was compiled, it took 0.078 seconds while i see fellow java coders clocking speed of 0.031, can you suggesting better classes to read inputs instead of the one i used, all other suggestions are highly welcome

#include <iostream>
using namespace std;
int main()
{
    int a=1, b=5, sum=0;
    sum=a+b;
    cout<<sum<<endl;
    return 0;
}

a = input()
b = input()

a = int(a)
b = int(b)
c = a+b
print c

this should be correct isn't it ?

import java.util.Scanner;
public class Summa {

    /**
     * @param args

    public static void main(String[] args) {
        // TODO Auto-generated method stub
Scanner scan=new Scanner( System.in);
System.out.println("Введите значение a");
int a;
a=scan.nextInt();
System.out.println("Введите значение b");
int b;
b=scan.nextInt();

System.out.println(" a + b = " + (a + b));

    }

}

what's the wrong!!! I've written this code in c++ and submitted under visual c++2010 but they don't accept it..why?????

using System;

public class Sum

    private static void Main()
    {
        string[] tokens = Console.ReadLine().Split(' ');
        Console.WriteLine(int.Parse(tokens[0]) + int.Parse(tokens[1]));
    }
}

import java.util.Scanner;

public class firstexercise{

public static void main(String[]args){
Scanner scanner=new Scanner(System.in);

int c=0;

System.out.println("Введите первое число.");
int a=scanner.nextInt();
System.out.println("Введите второе число.");
int b=scanner.nextInt();

c=a+b;

System.out.println("Ответ = " + c);

}


}

#include<iostream>
using namespace std;
int main()
{
 int a,b;
cin>>a>>b;
 cout<<a+b;
 return 0;
}

#include <fstream>
using namespace std;

int main()
{
 ifstream fin("INPUT.TXT");
 ofstream fout("OUTPUT.TXT");
 int a,b;
 fin >> a >> b;
 fout << a + b;
 fin.close();
 fout.close();

}

#include <iostream>
int main() {
using namespace std;
int a, b, buffer;
cin>>a>>b;
int *mass=new int[b];
int *deep=new int[33180];
for (int i4=0; i4<b; i4++) {
mass[i4]=0;
deep[i4]=1200;
}
for (int i5=b; i5<33180; i5++) {
deep[i5]=a;
}
for (int i6=0; i6<33180; i6++) {
for (int i9=1; i9<33180; i9++) {
if  (deep[i9-1]>deep[i9]) {
buffer=deep[i9-1];
deep[i9-1]=deep[i9];
deep[i9]=buffer;
}
}
}
mass[0]=a;
mass[b-1]=b;
for (int i=0; i<b; i++) {
for (int i2=1; i2<b; i2++) {
if  (mass[i2-1]>mass[i2]) {
buffer=mass[i2-1];
mass[i2-1]=mass[i2];
mass[i2]=buffer;

}
int sum=0;
for (int i3=0; i3<b; i3++) {
sum+=mass[i3];
}
cout<<sum;
delete []deep;
delete []mass;
return 0;
}

This solution works 1 second and output 1 if a=1 or b=1, and get AC!

ab = raw_input()
print int(ab[0]) + int(ab[2])

package timus;

class timus {

        public static void main (String args[])
        {
            int a = 1,b = 5;
            System.out.println(a+b);
        }
    }
