C :

#include<stdio.h>
int main(){
	int a,b,c;
	scanf("%d %d %d",&a,&b,&c);
	if(a+b>c){
		printf("%s","yes");
	}else{
		printf("%s","no");
	}
	return 0;
}

C++ :

#include<iostream>
using namespace std;
int main(){
	int a,b,c;
	cin>>a>>b>>c;
	if(a+b>c&&a+c>b&&c+b>c){
		cout<<"yes"<<endl;
		
	}else{
		cout<<"no"<<endl;
	}
}

Pascal :

var a,b,c:longint;
begin
  read(a,b,c);
  if a+b>c then writeln('yes') else writeln('no');
end.

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		@SuppressWarnings("resource")
		Scanner scanner=new Scanner(System.in);
		int a= scanner.nextInt();
		int b= scanner.nextInt();
		int c= scanner.nextInt();
		if (a+b>c) 
			System.out.println("yes");		
		else
			System.out.println("no");
		}
}

Python :

a,b,c = map(int, input().split() ) 
if a+b>c:
    print('yes')
else:
    print('no')
