Hello, i am new to this board and to c++.
anyway, this question i have is this...
i wrote this program, and although it is functional, i think it could
be written simpler. can anyone take a look at it and give me your
thoughts?
thank you
/* This is a program that generates letter grades
* and a +, -, or <blank> when given a numerical grade.
* Although functional I think it could be made easier.

#include <iostream.h>

int grade; // temp place holder
char final; // letter grade
char post; // +, -, or <blank>

{
// intro
cout << "This one is a little trickier." << endl;
cout << "You give me the number grade and I will return the
letter grade." << endl;
// input
cout << "Please enter the number grade: ";
cin >> num_grade;
if (num_grade >= 101 || num_grade <= -1)
cout << "Invalid input" << endl;
