  • This program is used to calculate the product of two floating-point numbers and print their result.
  • Three double data type variables a, b and product are initialized.
  • The program requests the user to enter two floating-point numbers using the scanf() function and store the inputs in a and b respectively.
  • The two variables a and b are them multiplied using the * operator and their result is stored in the variable product.
  • The printf() method is used to print the variable product and display the result on the screen.
  • The program exits using the return 0 statement.
