c++ Grading progeamm help

#include <iostream>
using  namespace std ;
int main() ; 

 {
      score and grade     // declare variables ;
 
      float total_score  // total weigted points ;

      char grade // letter  grade ;

      int A , B , C , D , F  ;	 	


	   // read in total score ;
	 
      cout << endl ;
      cout << "Enter total score (float, must be <= 100) : " ; 
      cin >> score ; 
	  	
	   if (score >= 85) ;
	 
		 grade = 'A' ;

	
	   else if (score >= 75);
	  
		  grade = 'B' ;
	
	   else if (score >=65) ;
	 
		   grade = 'C' ;
	 
	 
        else if (score >= 55) ;
	  
		     grade = 'D' ;
	  

	     else 

		      grade = 'F' ;
	 

	     // end if score
	 
	
     // display the result 

     ; cout << endl ; 
     cout << "Your grade for CMIS 102 is: " << endl ; 
	 

     return (0); // terminate with success
  

 }

This gives me an error - >.\Assignment 2.cpp(21) : error C2447: '{' : missing function header (old-style formal list?)

Remove the ; from int main();

You're going to have more semicolon problems throughout your code. (See if else statements)

This is what I get when I remove!!!

[jashbela]

Please help!!!!!! I don't know why?

[Sodabread]

1. Everything on one line after a // is commented out, including semicolons.
2. I'm assuming your "score and grade" text should be a comment. Make it one.
3. Your if/else statements aren't semicoloned properly.
4. Keep reading whatever you're learning C++ from. No offense, but it seems you don't yet have a firm grasp on syntax and how to form proper C++ statements.

[WaltP]

Read up on the semi-colon. You have no idea yet how/when/where to use them. Your book is the best place to learn this simple stuff.

[jashbela]

I fugured it out. semiclolons and varables ty

[jashbela]

Hi guys last help please.I am going to copy and paste. It works gives me results but says variable grade used with out initializing. What shoud I do?

int main() 
{

     float score ;
     char grade ;

     // read in total score 

     cout << endl ;
     cout << "Enter total score (float, must be <= 100) : " ; 
     cin >> score ; 
     
     if (score>=85) 
		 cout <<"The grade is A " << endl ;
	 else if (score>=75) 
	     cout <<"The grade is B " << endl ;
	 else if (score>=65)
	     cout <<"The grade is C " << endl ;
	 else if (score>=55)
	     cout <<"The grade is D " << endl ;
	 else 
	     cout<<"The grade is F " << endl ;


     // display the result 

     cout << endl ; 
     cout << "Your grade for CMIS 102 is: " << grade << endl ; 

     return (0); // terminate with success

[Sodabread]

You never actually set the grade variable to anything, so you're printing a variable with 'nothing' in it. I say 'nothing' because an uninitialized variable is full of garbage, not exactly nothing.

[jashbela]

So I still don't know what to do.

[jashbela]

I still need help. Ty, I would so appreciate it. I tried to read and find out but there is no answer to this .

[jashbela]

Ok, I don't know why but since I was having an error at that last line while debugging I took the line out
cout<< "your grade is " << endl

Now it debugs with out problem but need to know why?

I was simply frustrated so erased that line, lol

[WaltP]

What does the word initialize mean?

[jashbela]

I have no Idea so.......

[jashbela]

Please help me under stand

[WaltP]

unbelievable! Try This

[jashbela]

I know the definition I just dont know what to do to initialize the variable . I have tried every thing

[WaltP]

I know the definition I just dont know what to do to initialize the variable . I have tried every thing

Obviously not. What's the value of grade when you output it? Point to the line that loads the value you claim it has.

[jashbela]

Ty though. Should I put

char grade // declare the grade ;

? Is this what i need?

[jashbela]

I have tried setting grade = A but didnt work. so sorry to sound dumb but rally getting confused

TY

[jashbela]

One more question , when i remove the line

cout<< " Your garde is" << grade << endl ;

at the end why does it work?

[Sodabread]

You're close with grade = A, but since grade is a char, A needs to be a char, so you'll need to wrap it in single quotes.

If I may make a suggestion.. I think you might need to learn from a different source if you haven't learned yet how to initialize a variable but you've learned cin & if statements. Just doesn't make sense to me.

[jashbela]

Ty, for the help. I really haven't learned C++. In the class I am taking they want us to keep format, all I have to do declare variables and write if else statements. I am leaning this on my own. I figured out semicolon, if else , and variables. I kind of figured out cout and cin little bit.( i didn't have to, I was given that part)

Just was lost at erroe " variable grade is not initialized" and also why it works when I take last line out!

[Sodabread]

So you got everything figured out and working properly now?

[ben1996123]

This is how I made it.

#include <iostream>

using namespace std;

int main(){
    int score;
    
    cout << "Enter score: ";
    cin >> score;
    
    if(score > 100){
             cout << "Lies.";
    }
    else if (score >= 85){
             cout << "A";
    }
    else if (score >= 75){
             cout << "B";
    }
    else if (score >= 65){
             cout << "C";
    }
    else if (score >= 55){
             cout << "D";
    }
    else {
         cout << "F";
    }
    
    system("pause");
}

[jashbela]

yes working now. ty for all the replies.
