Program to Calculate the Exponential Series in C | C Program

Here's a C program to calculate the exponential series using For loop with output.

Formula of Exponential Series: The formula for sine series is -

Exponential Series

# include <stdio.h>
# include <conio.h>
void main() 
{ 
 int i, n, exp; 
 float x, sum = 1, t = 1 ; 
 clrscr() ; 
 printf("Enter the value for x : ") ; 
 scanf("%f", &x) ; 
 printf("\nEnter the value for n : ") ; 
 scanf("%d", &n) ; 
 for(i = 1 ; i < n + 1 ; i++) 
 { 
  exp = i ; 
  t = t * x / exp ; 
  sum = sum + t ; 
 } 
 printf("\nExponential Value of %f is : %8.4f", x, sum) ; 
 getch() ; 
}

Output of above program is

Enter the value for x : 2
Enter the value for n : 20
Exponential Value of 2.000000 is :   7.3891
