I need to make a program where the user inputs a grade and the program tells the user if its a pass (a,b, or c) or fail (d and below), then I need the program to output a counter of all the grades that have passed or failed
Herse my code *note I’m only using a and d to see if it will work* :

#include <iostream>
#include <string>

using namespace std;

int main(void)
{
	string name;
	string math;
	int a;
	int d;
	int matha;

	cout << "Enter name: n"
	cin >> name;

	cout << "Enter math grade " << name << " got: n"
	cin >> math;
	if (matha = a){
		cout << name << " passed n"; 
	}
	else if (matha = d){
		cout << name << " failed n";
	}
	
	system("PAUSE");
	return 0;
}

#include <iostream>

#include <string>

using namespace std;

int main(void)

{

string name;

string math;

int a;

int d;

int matha;

cout << "Enter name: n"

cin >> name;

cout << "Enter math grade " << name << " got: n"

cin >> math;

if (matha = a){

cout << name << " passed n";

}

else if (matha = d){

cout << name << " failed n";

}

system("PAUSE");

return 0;

}

but when I run it, its meant to say fail.

can anyone point me in the right direction please?

Thanks Geekrockergal

could do:

#include <iostream>
#include <string>

using namespace std;

int main(void)
{
	string name;
	string math;
	int a;
	int d;
	char mathGrade;

	cout << "Enter name: n";
	cin >> name;

	cout << "Enter math grade " << name << " got: n";
	cin >> mathGrade;
	if ( tolower ( mathGrade ) == 'a' ||  tolower ( mathGrade ) == 'b'  || tolower ( mathGrade ) == 'c' )
		cout << name << " passed n";
	else if ( tolower ( mathGrade ) == 'd' || tolower ( mathGrade ) == 'f' )
		cout << name << " failed n";
	system("PAUSE");
	
	return 0;
}

#include <iostream>

#include <string>

using namespace std;

int main(void)

{

string name;

string math;

int a;

int d;

char mathGrade;

cout << "Enter name: n";

cin >> name;

cout << "Enter math grade " << name << " got: n";

cin >> mathGrade;

if ( tolower ( mathGrade ) == 'a' || tolower ( mathGrade ) == 'b' || tolower ( mathGrade ) == 'c' )
