Gomok c++ algorithms

You are required to develop a computer program in C++ that reads in a board size from a file, implements the game of Gomoku for the given size, implements two different algorithms that will compete against each other and record the games in an output file. Some rules about Gomoku: » Algorithm 1 will take alternating turns with algorithm 2 at placing their markers in the grid

This is my question. Have spent hours researching it, and am new to coding and just need some help with where to start. Would prefer to not use the minimax function.

here is the question aswell:
