Of course you would need another function (probably just main) to collect input.

I think you could improve the speed of development by taking uncessary
complexity. For instance, the most complicated part of your code is also
unecessary; instead of preparing the board with complicated potentially buggy
loops just:
int board[8][8] = {{10,8,9,11,12,9,8,10},
{7,7,7,7,7,7,7,7},
{0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0},
{1,1,1,1,1,1,1,1},
{4,2,3,5,6,3,2,4}};
or something similar.
