C Program to Generate Multiplication Table with Example

Wanna create a multiplication table for a number? This C program lets you whip one up easily! Just input a number, and it'll show you the products from 1 to 10. Let's dive into how to build this.

Prerequisites for the C Program to Generate Multiplication Table

Before you start, ensure you understand the following:

• Using a for loop in C.
• The arithmetic operators * and =.
• Basic input/output functions like printf and scanf.
• Any C compiler such as GCC 9 or newer — or just run it in the EduSeekho online compiler.

Source Code of C Program to Generate Multiplication Table

Here's the complete source code to generate a multiplication table in C.

#include <stdio.h>

int main() {
    int n, i, product;
    // Prompt user for an integer
    printf("Enter an integer: ");
    scanf("%d", &n);

    // Loop from 1 to 10
    for (i = 1; i <= 10; i++) {
        product = n * i;
        // Print the result
        printf("%d x %d = %d\n", n, i, product);
    }

    return 0;
}

Output of the Generate Multiplication Table Program

When you run the program and input a number, it prints the multiplication table up to 10.

Enter an integer: 5
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45
5 x 10 = 50

Algorithm to Generate Multiplication Table in C

Generating a multiplication table involves multiplying the input number with numbers 1 through 10. Here's how the program handles this step by step.

1. Read the integer n from the user.
2. Initialize i to 1.
3. Check if i is less than or equal to 10.
4. Calculate the product of n and i.
5. Print n, i, and the product.
6. Increment i by 1.
7. Repeat steps 3-6 until i is greater than 10.

  C --> D{"i <= 10?"}
  D -->|Yes| E["product = n * i"]
  E --> F["Print n, i, product"]
  F --> G[i = i + 1]
  G --> D
  D -->|No| H([End])

How the C Program to Generate Multiplication Table Works

Here's a detailed look at how the code operates line by line.

• The line #include <stdio.h> includes the standard input and output library, necessary for using printf and scanf.
• We declare an integer variable n to store the number whose table we want, and i and product to handle loop iteration and results.
• printf("Enter an integer: ") prompts the user to input an integer.
• scanf("%d", &n) reads the integer input and stores it in n.
• The for loop for (i = 1; i <= 10; i++) runs 10 times, iterating i from 1 to 10.
• Inside the loop, product = n * i calculates the current product.
• printf("%d x %d = %d\n", n, i, product) prints each line of the multiplication table.
• Finally, the program ends with return 0, signaling successful completion.

How Fast is the Generate Multiplication Table Program in C?

Analyzing the time and space complexity gives insight into the program's efficiency.

Time Complexity: O(1). The program runs a loop that executes exactly 10 times, regardless of the input number. The loop is for (i = 1; i <= 10; i++), and since it has a fixed number of iterations, the time complexity is constant. It's a constant time, always executing 10 iterations.

Space Complexity: O(1). It uses only a few integers: n, i, and product. These do not grow with input size, resulting in constant space usage regardless of the input.

Key takeaway: Using a loop for the multiplication table keeps things consistent and makes the code simpler.
