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;
}
Output
1.12
Product = 2.69
#2 Code Example with C Programming to enter two number
Code -
C Programming
printf("Enter two numbers: ");
scanf("%lf %lf", &a, &b); Output
1.12
Product = 2.69
#3 Code Example with C Programming to evaluated
Code -
C Programming
product = a * b;Output
1.12
Product = 2.69
#4 Code Example with C Programming
Code -
C Programming
printf("Product = %.2lf", product);Output
1.12
Product = 2.69
