Help with Running Counter!

[rawrilyle]

Hi, I have an assignment where I create a program that prompts user to select which math game they would like to play. I have successfully created a loop in which 5 questions are displayed and user inputs answer, and computer displays incorrect/correct. However, I would like to include a grade counter that allows the user to see their grade after they answer a question.

Thanks so much!

for (int count=1;count<6;count++)
                                {
                                int x1,x2,s,result,x3,sum=0;
                                srand(time(0));
                                x1=rand()%9+1;
                                x2=rand()%9+1;
                                x3=(x1+x2);
                                cout<<"\n"<<x1<<"+"<<x2<<"=?"<<endl;
                                cin>>result;
                                if (result==x3)
                                {cout<<"Correct. "<<x1<<"+"<<x2<<"="<<x3<<endl;
                                sum++;
                                cout<<"Your grade: "<<sum<<"/5"<<endl;}
                                if (result!=x3)
                                {cout<<"Incorrect. "<<x1<<"+"<<x2<<"="<<x3<<endl;
                                }
                                }

Line 13: You're doing integer division. Any number (sum) less than 5 divided by 5 is going to be 0.

Line 4: Do not call srand() within a loop or a random number function. srand() sets the RNG to a particular starting point. Calling srand() repeatedly can cause the RNG to return the same random numbers. srand() should be called ONCE at the beginning of main().
