inline double work(double in_heat, double out_heat, int cycle)

According to Thermodynamics second law, a thermal machine works in cycles receiving and losing heat and receiving or doing work. (Act as a machine or refrigerator)

$$Q_{1} - Q_{2} = W$$

(1)

$$Q_{1} ~~ is ~the~ incoming~ heat\par Q_{2} ~~ is~ the~ lost~ heat\par W ~~ is~ the~ work~ done~/~received$$

(2)

Example 1

The work done by a machine receiving 10J of heat and losing 4J to ambient, with cycle in clockwise direction

printf("%.0f",work(10,4,1));

Output: 6

Parameters

in_heat

The incoming heat (Any value)

out_heat

The lost heat to ambient(Any value)

cycle

The cycle direction ( 1 for clockwise, -1 for counter-clockwise )

Returns

The work done by the machine

Input for cycle must be -1 or 1 (counter-clockwise and clockwise), if a value different from those is inputted, the function will return 0.
