C++ Error Message?

I am using C++ to write a program for class, and I keep getting the following error: "error C2064: term does not evaluate to a function taking 2 arguments".





The error is in reference to this function call:


grade (gradeBook, grade);


and here is the prototype and the actual function:


void grade(studentInfo gradeBook [ ], char%26amp;);


void grade (studentInfo gradeBook [ ], char%26amp; grade)


{


int student;


int score;





for (student=0; student%26lt;=10-1;student++)


{





if (70 %26lt; score %26lt; 90)


grade = 'S';


else if ( score %26gt; 90)


grade = 'O';


else (score %26lt; 70);


grade = 'U';


}


}

C++ Error Message?
You have a function named 'grade' but inside your 'for' loop you have assignment statements such as 'grade = 'S';' which use 'grade' as a variable, but never declared a variable named 'grade' or told the compiler what data type the variable 'grade' is.





Also you cannot use the same identifier 'grade' for the name of a function and also as the name of a variable. So use a different name for the variable such as 'myGrade'. But before you assign any value to 'myGrade' you must declare that it is a variable of type char by writing the statement


char myGrade;





A third issue is in your conditional


if(70 %26lt; score %26lt; 90)





That is incorrect syntax. This conditional is proper:


if(70 %26lt; score %26amp;%26amp; score %26lt; 90)





But if you use 'myScore' as the variable name, then that would be





if(70 %26lt; myScore %26amp;%26amp; myScore %26lt; 90)





If you want to include values of 70 and 90, then you might want to use %26lt;= instead of %26lt;.
Reply:Your function signature is different to the function itself.





Change the first





void grade(studentInfo gradeBook [ ], char%26amp;);





to





void grade(studentInfo gradeBook [ ], char%26amp; grade);
