2d Array Determine where chars change

Vyperhate (13)
Ok honestly had no idea how to word the title. I need help on this quick as it's already past due and I've been struggling with it for a while now.

Basically I am generating a yard, then I place bones randomly in that yard, then a dog digs random holes in the yard, anywhere where the dog digs a hole and finds a bone an "x" is placed, otherwise an "H" is placed. I have everything done but no matter what I do I cannot figure out how to determine when a bone is found and replace the "B" with an "x"...

Here is the code so far:

On line 118: if(yard[R][C] = 'B') is an assignment. Change it to if(yard[R][C] == 'B') for comparison
