Write a C Program to compute x^n/n!.

Problem statement:- Program to compute x^n/n!

 Data requirement:-

   Input Data:- n,x

  Output Data:-result

  Additional Data :-i,fact

Program in C
  
Here is the source code of the C Program to compute x^n/n!.

#include<stdio.h>//Printf,scanf defination
#include<math.h>
int main()
{
int n,x,i,fact=1;
double result;

//Get the n and x value
printf("Enter the n and x Value:");
scanf("%d%d",&n,&x);
//compute the n factorial
for(i=1;i<=n;i++)
{
fact*=i;
}

//compute the x^n/n!
result=pow(x,n)/fact;

//Display the value of x^n/n!
printf("Result(x^n/n!)=%lf\n",result);
}

Input/Output:
Enter the n and x Value:5
4
Result(x^n/n!)=8.533333
