problem statement

string - Ad Hoc

As you can see in the problem description, some characters with their costs are given to you, a passage comes after that, and you have to count each character in that passage and find out how much money publisher must pay for a text, characters that are not given a specific cost have to be considered with cost 0.
After I read and count occurrence of each character, I find the cost of the passage with these two lines of code :
        for(int i = 0; i < 400; i ++)
            cent += occurrence[i] * cost[i];
and print output in this manner :
        int dol = cent / 100;
        cent %= 100;
        cout << dol << "." << (cent < 10 ? "0": "") << cent << "$" << endl;
