"No operator '!=' matches these operands."
Hey guys I'm writing a program and attempting to use a Sentinel but the "not equal to" operator != doesn't seem to be working for me.
Can anyone help me correct what is wrong within my code?

Look at the types of the things you are trying to compare. One is an int, the other is an std::string.
Should I simply change it to
1

while (score != SENTINEL)

To fix?
EDIT:
When I did this it gave me 2 different errors for uninitialized local variables for 'score' and 'topScore'

But now I am getting an uninitialized local variable error for 'topScore' in
int topScore;
Should be :
int topScore = 0;
