I am currently coding a basic tic tac toe game in c++ for my university assessment and keep receiving an error

In the function setBoard(), I am trying to set a position on the grid to be equal to a X or a O depending on the player but keep receiving this error while debugging the program.

Unhandled exception at 0x008439FF in TicTacToe.exe: 0xC0000005: Access violation reading location 0x33B80330. the error is in the function setBoard() where it reads:

if (g_acBoard[iX][iY] == ' ')
