	 printf("Enter two numbers :");    
     product = a * b;                
     printf("product of two numbers :%d",product);
Enter two numbers :5 8    /* say a = 5 & b = 8 */.
product of two numbers :40

Program Explanation

Step 1: Include header files (#include<stdio.h> and #include<conio.h>).

Step 2: Start with main function with return type.

Step 3: parenthesis to start and end the program { }.

Step 4: declare the variables with data types. i.e, values of 'a' and 'b' are of integer type, so we declare 'a' and 'b' variable with "int" data type. We also declare 'product' as int variable because it returns an integer value.

Step 5: Use output function printf() to print the output on the screen.

Step 6: use input function scanf() to get input from the user.

Step 7: using getch() function to hold the screen.
