    Moved to C++ programming forum.

    One possible problem is because you are assigning (matha = a) instead of comparing for equality (matha == a).

    Oh, and kindly indent your code more consistently and get rid of those superfluous empty statements.

    okay but its for C not C++ and please explain what you mean by indentting my code??
    *edit* Ive placed two == but now it doesnt state whether its a pass or fail it completely ignores that ???

    Well, you are nearly there, but a little more consistency is good. For example:
    Code:
    #include <iostream>
    #include <string>
    #include <cstdlib>
    
    using namespace std;
    
    int main()
    {
        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;
    }
    I took the liberty of removing the superfluous empty statements as including <cstdlib> which is needed for system() (which you do not need to use in the first place), but I did not make the fixes I suggested.
