Please help!!!
i have a university assignment to do in C++ and i dunno what code to write can anyone help me?
this is my assignment:
develop a C program to approximately calculate the value of e(to the power x) applying this followong infinite series:
e(to power x) = (sum of sign, with infinity above it, and (n=o below) (x(to power n/n factorial)
in the range n=0,1...,10, and x=0.8
what is this? please help!
How about starting with a function to calculate factorial(n)
Since math.h already has a pow() function, the rest is just a loop

Make your mind up - which is it?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
argh
Ok ur talkin to someone whos never done programming before. This is a random compulsory assignment. Iv been told we are programming in c++, and the bit i wrote was copied word for word from the sheet. so i assume they mean write a c++ program for ....
so i need to start form the beginning basically...
No basic instruction in C++ at all - like how to even compile the simplest of "hello world" programs?
Do you have a compiler set up which you can use?

I know the basic stuff u start with, like
#include <stdio.h>
main()
{
but they dont tell me about how to write the code for this particular equation...
Short of handing your homework to you on a plate (it's not likely to happen), this is as far as I can go showing you the way.
All you need do is uncomment the fact_term bits and work out how to calculate factorial(n)Code:#include <iostream> #include <cmath> using namespace std; int main() { double x = 0.8; double sum = 0.0; for ( int n = 0 ; n <= 10 ; n++ ) { double pow_term = pow(x,n); // double fact_term = ..... cout << "n=" << n << " pow(x,n)= " << pow_term << endl; sum = sum + pow_term /* / fact_term */; } cout << "Sum = " << sum << endl; return 0; }
