main is the only function which is called from outside of the program. the code for invoking the main function is written inside something called as a "startup code". this startup code contains the prototype of main function. the main function is "called" from within this startup code which then is linked by linker to its definition created by the programmer. The linker, as we know, is responsible for linking object code to lib code. Along with these two codes, it also links startup code to create the executable file.

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!+....
