help urgent

how do you use the if function and how would one declare its values, example for a grading system for school

#include (iostream)

using namespace std;

char letter-grade;


cout<<"enter grade";
cin>>grade;

if (grade>= 90)
letter -grade = "A";

what am I missing, and how do I close the statement once it reaches to F

[code]
if (grade>= 90)
letter_grade = 'A';
[/codeif is a statement NOT a function

What you have here is a complete if statement, it needs no closing, note I have corrected your string constant to a character constant and made your variable name valid.

If you want to execute more than 1 line of code when the condition is true then put in braces and have an if block

if (grade>= 90)
{
  letter_grade = "A";
  totalA++;
}

You did not show code extending to 'F' so it is a little hard to know what you mean however are you talking about if - else if - else

if (grade>= 90)
{
  letter_grade = 'A';
}
else if (grade>= 80)
{
  letter_grade = 'B';
}
else
{
  letter_grade = 'F';
}

Thank you for you taking time out to guide me in the right direction. I am using Visual Studio 6.0, and I was unclear to write the statement so that it is recognize, you hit on the nose with the rest of the code you provided. I just do not know what shoud I start with before letter grade or IF .

What you had in your original post looks about right to me
