/*
Problem: Make a function that calculates series capacitor circuit or parallel capacitor circuit. For the function capacitor values 
(unit F) C1,C2,C2,Cn and circuit type "serial" or "parallel" and capacitor count are passed as a parameters. Unit for result is µF.
For example:

Test								| Result
------------------------------------------------------------------------
float C1=10E-6;							| 2.000
float C2=10E-6;							|
float C3=10E-6;							|
float C4=10E-6;							|
float C5=10E-6;							|
								|
float capacitor_values[]={C1,C2,C3,C4,C5};			|
int len = sizeof(capacitor_values)/sizeof(capacitor_values[0]);	|
int circuit_type=2; //1=parallel circuit, 2=serial circuit 	|
printf("%.3f",circuit(capacitor_values,circuit_type,len)); 	|
