Assignment Factorial and Power
Assignment: Factorial and Power
This assignment is to help you review C-programming for Numerical Programming.
==Do NOT use Chat-GPT and online materials. You can do it by yourself==.
Problem
Q1. Create power(x,N) function that returns
double power(double x, int N);
Q2. Create factorial(x) function that returns
double factorial(int x);
Hint
Preparation
You must complete the following tutorials first.
Process
Create a new project “ Assignment_powerNfactorial” with Visual Studio Community.
It should be under the designated folder of
\NP\assignment\
C:\...\...\source\repos\NP\assignment\Assignment_powerNfactorial\
Create a new source file and name it as “Assignment_powerNfactorial_yourName.cpp”
Copy the source code below or from this link: Assignment_powerNfactorial_student.cpp
Fill in the definitions of power() and factorial()
Run the code and check the answers
Capture the output window and paste in the report
Submit
Submit as “Assignment_powerNfactorial_yourName.zip” that includes
(1) Report: “Assignment_powerNfactorial_yourName.pdf”
A report that shows the results by capturing the output screen
Download a simple report template
(2) Source code
submit only “Assignment_powerNfactorial_yourName.cpp”
Code
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
double factorial(int _x);
double power(double _x, int N);
int main(int argc, char* argv[])
{
double x = 2.5;
int N = 5;
double y1 = 1;
double y2 = 1;
y1 = power(x, N);
y2 = factorial(N);
printf("\n\n");
printf("=======================================\n");
printf(" power(%f,%d ) Calculation \n", x, N);
printf("=======================================\n");
printf(" - My result = %3.12f \n", y1);
printf(" - Math.h result = %3.12f \n", pow(x, N));
printf(" - absolute err. = %3.12f \n", y1 - pow(x, N));
printf("=======================================\n");
printf("\n\n");
printf("=======================================\n");
printf(" factorial( %d) Calculation \n", N);
printf("=======================================\n");
printf(" - My result = %.0f \n", y2);
printf("=======================================\n");
system("pause");
return 0;
}
// power fuction
double power(double x, int N)
{
// [TODO] add your algorithm here
// [TODO] add your algorithm here
return y;
}
// factorial function
double factorial(int N)
{
double y = 1;
for (int k = 2; k <= N; k++)
// [TODO] add your algorithm here
return y;
}
