When I try to run this code through the compiler, I get the error:
expression result unused
referring to the line
cents - 25;
How do I fix this error? How exactly do I "use" the expression result? I tried assigning it to a variable, but that didn't work because the variable cents wasn't updated so the loop kept running forever.
while (cents > 25)
{
cents - 25 ;
count++ ;
}
It's because you did a calculation and didn't do anything with it. You have cents - 25; Where are you putting the result?
All of these would work:
int change = cents - 25;
cents = cents - 25;
cents -= 25;
The infinite loop is another story. To fix that loop, you'd use either of the latter two.
