Introduction to C++ Branching

I can't come up with a valid solution to homework number 3.  The initial code (in number 2) worked as intended but I get an error when I add in the statement providing an invalid grade when < 0 or > 100.  I've also tried breaking that line into "if (rawGrade < 0 or > 100) {" and
"if (rawGrade < 0) or (rawGrade > 100) {" but I always get an error that it doesn't like the "or" (even if I use the || instead of the word).  Why?


#include "stdafx.h"
#include <iostream>
using namespace std;

int main ()
{
cout << "Welcome to the Easy Going University Grade System!" << endl;
cout << "Please enter the student's raw grade: " ;
int rawGrade;
cin >> rawGrade;

if (rawGrade < 0 or rawGrade > 100) {
cout << "Invalid grade!";
}

if (rawGrade > 60) {
cout << "You passed!" << endl;}

else {
int curve = (rawGrade * .5); // Determine amount of curve (50% of raw grade)
int curvedGrade = rawGrade + curve; // add curve to initial grade
cout << "The grade is curved by " << curve << " points." << endl;
cout << "Your total grade is " << curvedGrade << "." << endl;

if (curvedGrade <= 60) {
cout << "You failed!  No refunds!" << endl; }
else {
cout << "You passed!" << endl; }}
return 0;
}

17 * 5 whatever that adds up to I'm not gonna work it out???? Jesus! What Master's Degree Professional doesn't know this right off the top of their head? It's 85! I'm sorry, educator.com, but I was cracking when I heard this.

This is the reason I think programming should be taught in schools as a shop elective where you can apply it to another field. No disrespect to programming majors, but if we teach our young students from grade school the basics, then have them keep on the course of taking programming as an elective, they'll become great programmers and professionals by the time they graduate college! Then they can go to grad school in any field of their choosing with this powerful skill: programming.
