C :

#include <stdio.h>

int main(void) {
	int a, b, c;
	scanf("%d%d", &a, &b);
	c = a * b;
	printf("%d", c);
	return 0;
}

C++ :

#include<cstdio>
using namespace std;
int main()
{
	int a,b,s;
	scanf("%d%d",&a,&b);
	s=a*b;
	printf("%d\n",s);
	return 0;
}

Pascal :

program yucong;
var
a,b,s:integer;
begin
read(a,b);
s:=a*b;
writeln(s);
readln;
end.

Java :

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner cin = new Scanner (System.in);
    while (cin.hasNext()){
        int a = cin.nextInt();
        int b =cin.nextInt();
        System.out.println(a*b);
    }
  }
}
