#include<stdio.h>
int main()
{
int a,i,f;
printf("Enter a number: ");
scanf("%d",&a);
f=0;
i=2;
while(i <= a/2)
{
if(a%i == 0)
{
f=1;
break;
}
i++;
}
if(f==0)
printf("Prime Number")
else
printf("Not Prime Number");
return 0;
}

the factorial of non-negative integer n is written n! and is defined as follows: n!=n*(n-1)*(n-2)........1(for values of n greater than or equal to 1 and n!=1(for n=0) Perform the following 1.write a c program that reads a non-negative integer and computes and prints its factorial. 2. write a C program that estimates the value of the mathematical constant e by using the formula: e=1+1/!+1/2!+1/3!+.... 3. write a c program the computes the value ex by using the formula ex=1+x/1!+xsquare/2!+xcube/3!+....
