Function: One of the building blocks of C++ program is functions; it contains a group of statements which are used to perform a specific task and the executable segments in a program. The function “main()” is the most important function in a program, because the “main()” function serves as the starting point to execute a program. The main advantage of using function is reusability of code and it reduces the size of the program, because once the code is written to perform a task in a program, it is reused in many places in the same program or in different programs.

Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.
