C Program to Implement e^x Function
This C Program finds the value of exponential function e^(x),given x and n
#include<stdio.h>
#include<math.h>
int x;
int n,u;
int fact(int n)
{
if (n==1)
return (1);
else
return(n*fact(n-1));
}
int findex()
{
int sum=0,ex,numr,denr;
int i;
for(i=0;i<=n;i++)
{
numr=pow(x,i);
denr=fact(i);
ex=numr/denr;
sum+=ex;
}
printf("ne^x = %d t %d n",sum,ex);
}
main()
{
printf("Enter the Value for 'X' and 'N' and Upper Limitn");
scanf("%d %d %d",&x,&n,&u);
findex();
}
