Help me with my program please.

Question

So if anyone could tell me what i need to do here I would be really grateful. I'm really new to c++.

#include <iostream>
using namespace std;

int chooseGrade()
{
cout << "What is the grade";
int grade;
cin >> grade;
return grade;
}

int main()
{
int grade = chooseGrade();
if (grade == 100) {
cout << "A+";
}
if (grade >=75 && <100) {
cout << "B";
}
if (grade >=50 && <75) {
cout << "C";
}
}

The error is error: expected primary-expression before '<' token

Answer 1

(grade >= 75 && grade < 100)
(grade >= 50 && grade < 75)

You cannot omit the variable for the evaluation of the second condition in the statement.
