Step-by-step explanation:
printf("Enter two numbers: "); scanf("%lf %lf", &a, &b);
Then, the product of a and b is evaluated and the result is stored in product.
product = a * b;
Finally, product is displayed on the screen using printf().
printf("Product = %.2lf", product);
Notice that, the result is rounded off to the second decimal place using %.2lf conversion character.
