**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.

It then calculates the total value of the integer based on the formula x - 1/3!x^3 + 1/5!x^5 - 1/7!x^7 + 1/9!x^9.

It then outputs the final answer using the 'cout' command.

**Sample Input** **3** **Sample Output** **Total = 0.14112**
