Q1. The value of Eulers number - e is given by - e = 1 + (1/(1!)) + (1/(2!)) + (1/(3!)) + (1/(4!)) + Write a C program to evaluate the value of e in a while loop that terminates when the difference between two successive approximations differs by less than 1e-6. Use the factorial function #include long factorial(int); int main() { int num=0; printf("Enter a number less than 20: "); scanf("%d",&num); if(0
