How to Write a C Program to Calculate the Product of Odd Integers from 1 to 15 Using a FOR Loop

The task at hand involves writing a C program that calculates the product of all odd integers from 1 to 15. This can be achieved by utilizing a FOR loop. The steps involved in accomplishing this are straightforward and will be explained in both English and C code.

Understanding the Requirements

The goal is to write a C program that computes the product of the odd integers from 1 to 15. This requires a good understanding of the FOR loop and how to manipulate variables to achieve the desired outcome.

Steps to Write the Program

Declare the necessary variables: You need two variables: count for the loop control and product to hold the product. Initialize product to 1: The initial value of product should be set to 1, as this will not affect the product. Use a FOR loop: Create a FOR loop that iterates through the odd integers from 1 to 15. Multiply product by the current odd integer: During each iteration of the loop, multiply product by the current value of count.

Complete Example in C

Here is a complete example of the C program that accomplishes the task:

#include stdio.h
int main() {
    int count, product  1; // Initialize product to 1
    // Loop through odd integers from 1 to 15
    for (count  1; count  15; count   2)
    {
        product  product * count; // Multiply product by the current odd integer
    }
    // Print the result
    printf("Product is: %d
", product);
    return 0;
}

Explanation of the C Program

The FOR loop starts with count initialized to 1 and continues as long as count is less than or equal to 15.

The increment count 2 ensures that only odd integers are considered (1, 3, 5, ..., 15).

Inside the loop, product is updated by multiplying it with the current value of count.

Finally, the program prints the resulting product after the loop completes, which will correctly display the product of all odd integers from 1 to 15.

Breaking Down the Process

This problem may seem daunting at first, but it simplifies to following a few key steps:

Initiate the loop: Begin with a loop that iterates through all integers from 1 to 15. Select the increment: Use a step of 2 to only consider odd integers (1, 3, 5, ..., 15).

Why This is Your Homework

This exercise is designed to help you master the usage of structural elements in programming, specifically the FOR loop. Initializing product to 1 is trivial, and the structure of the loop is straightforward. The goal is to understand the process and to practice basic programming concepts.

Final C Program

To complete the program, you would need to:

Initialize product to 1. Iterate through the odd integers from 1 to 15 using a FOR loop. Multiply product by count during each iteration. Print the final product value.

#include stdio.h
int main() {
    int count;
    int product  1; // Initialize product to 1
    // Loop through odd integers from 1 to 15
    for (count  1; count  15; count   2) {
        product  product * count; // Multiply product by the current odd integer
    }
    // Print the result
    printf("Product of odd integers from 1 to 15: %d
", product);
    return 0;
}
