C Program for Multiplication of Two Numbers

In this blog post, we will checkout the C Program for Multiplication of Two Numbers.

Algorithm to Add Two Numbers in C

To create a C Program for Multiplication of Two Numbers, you can follow this algorithm.

Algorithm:

1. Start: Begin the process.
2. Input two numbers: Prompt the user to input the two numbers.
3. Multiply both the numbers: Use the formula num1 * num2 to calculate the multiplication.
4. Display answer: Show the calculated answer to the user.
5. End: Conclude the process.

C Program to Multiply Two Numbers

#include <stdio.h>

int main() {
    double num1, num2, product;
    
    // Ask the user for two numbers
    printf("Enter first number: ");
    scanf("%lf", &num1);
    
    printf("Enter second number: ");
    scanf("%lf", &num2);
    
    // Multiply the numbers
    product = num1 * num2;
    
    // Display the result
    printf("The multiplication of %lf and %lf: %.2lf\n", product);
    
    return 0;
}

Output

Explanation

• Step 1: The program starts by including the standard input-output library stdio.h for basic input/output operations.
• Step 2: In the main function, three integer variables are declared: number1, number2, and result.
• Step 3: The program then prompts the user to enter the first and second numbers, which are read and stored in number1 and number2 respectively using scanf.
• Step 4: The product is calculated.
• Step 5: Finally, the program prints the result using printf.

Time Complexity: The time complexity of this program is O(1).

Space Complexity: The space complexity of the program is also O(1).
