e is a mathematical constant that is the base for the natural logarithm. It is also known as Euler's number. One way to calculate e is by using the following converging series, - n! Where n! is the factorial of the integer n which is the product of all positive integers less than or equal to n. n! given by, N=0 n n! = n k=1 n=0 is a special case where O! = 1. A computer program can be used to find the value of e based on the user input n. If n = 4, then the result of e should be as follows. 1 1 1 1 1 + + + + == 2.70833333333333 O! 1! 2! 3!' 4! Hint: Use the following statement to calculate the factorial int result = 1; if (f == 0 || f == 1){ return 1; } for(int i = 2; i
