C++ Programming : Program 31-A
Program to enter an integer and print its total value based on the formula
'x - 1/3!x^3 + 1/5!x^5 - 1/7!x^7 + 1/9!x^9'
#include <iostream.h> #include <conio.h> #include <math.h> int main() { clrscr(); float factorial=1; float num,tot,term,total; int i,n=20,index,j=1; cout << "Enter a single-digit integer : \n"; cin>>num; tot=num; total=num; for(i=2,index=3;i<=n;i++,index+=2) { for(j=1,factorial=1;j<=index;j++) factorial*=j; tot=tot*pow((double)(-1),(double)(2*i-1))*num*num; term=tot/factorial; total+=term; } cout << "Total = " << total << endl; getch(); return 0; }
This program takes in an integer num as a screen input from the user.
