To find the value of ex 

The program

#include<stdio.h>

int main()

{

 int i, n;

 float x, sum=1, t=1;

 printf("-:EXPONENTIAL POWER SERIES:- \n\n");

 printf("ENTER THE VALUE OF x of exp(x) SERIES: ");

 scanf("%f",&x);

 printf("ENTER THE LIMIT UPTO WHICH YOU WANT TO EXPAND THE SERIES: ");

 scanf("%d",&n);

 for(i=1;i<=n;i++)

 {

 t=t*x/i;

 sum=sum+t;

 }

 printf("\n THE VALUE OF Exp(%f) is : %.4f ",x, sum);

 }
