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, 0 Where n! is the factorial of the integer a which is the product of all positive integers less than or equal to n. n! given by + + 1 1 + + 2! 3!4! 0! n=0 is a special case where I = 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 = 2.70833333333333 1! Hint: Use the following statement to calculate the factorial int result = 1; if (f == 0 || 1 == 1) return 1: 1 for(int i = 2; i Write the code with the following specifications to solve for the calculation of e: Based on the given formula e, write a class called convergenceseries that contains o necessary data member(s) o necessary member functions to manipulate the data member(s) and output the result of e. o constructor to initialize some or all of the data member(s) The data file input.txt contains five values that correspond to the values of n. Write the program to read the file and calculate e from every value of n. DONA
