Polynomial Time

The problems for which the deterministic polynomial-time algorithm exists belong to the complexity class (p) and it is central in the field of computational complexity theory. According to Cobham’s thesis, polynomial time is a synonym for “feasible”, “fast”, and “efficient”.

Question

C++ language 1.2

Consider a program that receives two coordinates in a plane and prints the slope of the line
that connects them.
double x_1, y1,x2, y_2;
cin>>x_1>>y_1>>x_2>>y_2;
double slope;
slope=(y_2-y-1)/(x2-x_1);
cout<<slope;
This program works perfectly most of the time, but in some cases, it doesn't print anything,
an example of such cases is the input 1214. Explain why this is happening.
