Operator '&&' cannot be applied to operand of type 'bool' and 'int'

Question

I have an if elseif statement to check marks and grade the marks according to the condition.

int marks;
string grade;

if (marks>=80 && marks!>         


        

Answer 1

Other answers have made it known that the main problem is that !> isn't an operator.

I'd like to suggest that since you're testing whether marks lies within particular ranges that you take an additional further step to format your conditional expressions to use the following pattern:

if (80 <= marks && marks <= 100)
{
  grade = "A1";
}
else if (70 <= marks && marks <= 79)
{
  grade = "A2";
}

It's a simple and maybe subtle change, but I think it makes the range check intent much more clear.
