It will print hello with length of 5.Because return value of
printf is length of that string.

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!+....
