    using radom number with if else if else

    Code:
    #include<iostream>
    #include<cmath>
    using namespace std;
    int main()
    {
    	int answer = rand;
    	int rand;
    	cout << "How many gumballs are in the machine.\n";
    	do{
    		cin >> answer;
    		if (answer < rand)
    		{ 
    			cout << "To low" << endl;
    		}
    		else if (answer > rand)
    		{
    			cout << "To high" << endl;
    		}
    		else
    		{
    			cout << "Good job now u can eat them.\n";
    		}
    	}while (answer != rand);
    	system("pause");
    	return 0;
    }
    error:

    Do you know how to call a function? rand is a function (which you should not reuse as a variable name). And you should seed the random number generator at the start of your program, before you generate any numbers. rand(3): pseudo-random number generator - Linux man page

    Work on the logic on paper first. You're not even close at the moment. Search the forum for examples on how to use random numbers as well....this is a frequently discussed subject.
