Hello

I have 4 problems to solve out of 4 I solved 3 but problem mention below is painfull, I am not able to find how I will interchange the '+' '-' operator. I need some code. I am using Turbo C++

Write a C++ function having two value parameters X and M with result type float to find sum of series given:

1-X+1/2!X2 – 1/3!X3+1/4!X4+…..+ 1/M!XM

Thank you.
