Type conversion in C++ refers to the process of converting a variable from one data type to another. To perform operations on variables of different data types we need to convert the variables to the same data type using implicit or explicit type conversion methods. Implicit conversion is done …

WebThe convention of using colors originates from coloring the countries of a map, where each face is literally colored. This was generalized to coloring the faces of a graph embedded in the plane. By planar duality it became coloring the vertices, and in this form it generalizes to all graphs. In mathematical and computer representations, it is ...
