C Program Alternating Sign Power Factorial Series

Introduction

In this tutorial, we will learn about C Program Alternating Sign Power Factorial Series. This is a crucial concept widely used in software development.

Implementation Example

Here is the complete source code to demonstrate how this works in practice:

#include <stdio.h>
#include <math.h>

long factorial(int n) {
    if (n == 0) return 1;
    long f = 1;
    for(int i=1; i<=n; i++) f *= i;
    return f;
}

int main() {
    // Series: x - x^3/3! + x^5/5! - ... (sin(x) expansion)
    int n = 5;
    float x = 2.0;
    float sum = 0;
    int sign = 1;
    
    for(int i=1; i<=n; i+=2) {
        sum += sign * (pow(x, i) / factorial(i));
        sign *= -1;
    }
    
    printf("Sum: %f
", sum);
    return 0;
}

Code Explanation

The code above illustrates the core logic required to implement C Program Alternating Sign Power Factorial Series. By breaking it down, we can observe the following:
