C :

#include<stdio.h>
int main(){
  int a, b, sum, diff;
  scanf("%d%d", &a, &b);
  sum = a + b;
  diff = a - b;
  printf("%d\n%d", sum, diff);
  return 0;
}

C++ :

#include<stdio.h>
int main()
{
	int a,b;
	int c;
	int e;
	scanf("%d%d",&a,&b);
	c = a + b;
	e = a - b;
	printf("%d\n%d\n",c,e);
	return 0;
}

Pascal :

var a,b:longint;
begin
  readln(a,b);
  writeln(a+b);
  writeln(a-b);
end.
