C :

#include <stdio.h>
int main()
{
	int a,b;
	scanf("%d%d",&a,&b);
	printf("PROD = %d",a*b);
	return 0;
 } 

C++ :

#include<stdio.h>
int main()
{
    int a,b,PROD;
    scanf("%d%d",&a,&b);
    PROD=a*b;
    printf("PROD = %d",PROD);
    return 0;
}

Java :

import java.util.Scanner;
import static java.lang.Math.abs;
public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a = scanner.nextInt();
        int b = scanner.nextInt();
        if (abs(a)<=10000 && abs(b)<=10000) {
        int c =a * b;
            System.out.println("PROD = "+c);
        }

    }
