Cant figure this out

Ch1156 (1999)
I cannot figure this out, i have a program that opens a text file and searches for the word to find and it does all that but it doesnt show how many instances of the word are in there.

= has higher precedence than != so line 71 is seen as
while(position = (storeText.find(strFind, position) != string::npos))
by the compiler. To fix this you have to put parentheses around the assignment.
while((position = storeText.find(strFind, position)) != string::npos)
