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!+....

Write the following function in C.
stripos — Find position of first occurrence of a case-
insensitive string
int stripos ( char* haystack, char* needle, int offset )
Returns the numeric position of the first occurrence of
needle in the
haystack string. Note that the needle may be a string of
one or more
characters. If needle is not found, stripos() will return -
1.
The function should not make use of any C library function
calls.
