## Algorithm

1. Include Header File: `#include ` includes the standard input/output library for functions like printf and scanf.
2. Main Function: int main() is the starting point of the program.
3. Variable Declaration: double a, b, product; declares three variables of type double to store the two input numbers (a and b) and their product (product).
4. User Input: printf("Enter two numbers: "); prompts the user to enter two numbers, and scanf("%lf %lf", &a, &b); reads these numbers from the user and stores them in variables a and b.
5. Calculation: product = a * b; calculates the product of the two input numbers and stores the result in the variable product.
6. Output: printf("Product = %.2lf", product); displays the product with two decimal points.
7. Return Statement: return 0; indicates that the program has executed successfully.

## Code Examples

### #1 Program to Multiply Two Numbers

```Code - C Programming```

``````#include <stdio.h>
int main() {
double a, b, product;
printf("Enter two numbers: ");
scanf("%lf %lf", &a, &b);

// Calculating product
product = a * b;

// %.2lf displays number up to 2 decimal point
printf("Product = %.2lf", product);

return 0;
}
``````
Copy The Code &

Output

cmd
Enter two numbers: 2.4
1.12
Product = 2.69
