Write a C++ Program to find the Sum of the Series, 1 – x/2! + x^2/3! – x^3/4! + x^4/5! - …….. to n termsSum of 1 – x/2! + x^2/3! – x^3/4! + x^4/5! - …….. + n series in C++ Programming Language

Code Sample 1 (for Dev C++ & CodeBlocks) 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

#include<iostream> #include<math.h> using namespace std; int main() { int x, n; double s=0; cout<<"Enter the value of x:-"<<endl; cin>>x; cout<<endl<<"Enter the number of terms (n):-"<<endl; cin>>n; for( int i=0; i<=n;i++) { int f=1; for(int j=1;j<=(i+1);j++) { f=f*j; } s=s+pow(-1,(i+2))*(pow(x,i)/f); } cout<<"The value of the series stands - "<<s; return(0); }

Code Sample 2 (for Turbo C++)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

#include<iostream,h> #include<math.h> void main() { clrscr(); int x, n; double s=0; cout<<"Enter the value of x:-"<<endl; cin>>x; cout<<endl<<"Enter the number of terms (n):-"<<endl; cin>>n; for( int i=0; i<=n;i++) { int f=1; for(int j=1;j<=(i+1);j++) { f=f*j; } s=s+pow(-1,(i+2))*(pow(x,i)/f); } cout<<"The value of the series stands - "<<s; getch(); }

Sample Output:

Enter the x, i.e. the value of integer x which is in the series - 2

Enter the n i.e. max values of series - 4

Sum of the series: 0.466667

Topic covered here from class XI course is Programs on array manipulations (1D & 2D).
