C :

#include<stdio.h>
int main()
{
  int a,b;
  while(scanf("%d%d",&a,&b)!=EOF)
  {
    if(a>=b)
      printf("%d\n",a);
    else
      printf("%d\n",b);
  }
  return 0;
}

C++ :

#include <stdio.h>
int main()
{  
	int a,b;
	while(scanf("%d%d",&a,&b)!=EOF)
	{
		if(a>=b)
			printf("%d\n",a);
		else
			printf("%d\n",b);
	}
	
		return 0;
}

Pascal :

program aa;
var a,b:longint;

function  asd(i,j:longint):longint;
begin
  if i>j then asd:=i else asd:=j;
end;

begin
  while not eof do
    begin
      readln(a,b);
      writeln(asd(a,b));
    end;
end.
