Some help for a newbie!!!
I am new to this site and new to the C++ language, so pls bare with me. I am sure there is a very simple solution to this problem but it has got me stumped!!! I had to create a Counter class that has four counters. Think of it like this: [][][][]...it's not an array, each one is a separate variable that keeps a running total that is controlled by it's own function. Each one separately represents ones, tens, hundreds, and thousands(from right to left obviously) so when they reach 10 the 1 is carried over to the next one. Now, I have everything working except for the carry over.
Code:
#include <iostream.h>
class Counter
{
private:
int total1, total2, total3, total4, grandTotal;
int max;
int price1, price2, price3, price4;
public:
Counter();
void reset() { total1=0, total2=0, total3=0, total4=0, grandTotal; }
void incrl1();
void incrl10();
void incrl100();
void incrl1000();
void overflow() { cout << "You have exceeded your limit!"; }
void display();
};
Counter::Counter()
{
max=9999, total1=0, total2=0, total3=0, total4=0, grandTotal=0;
price1=0, price2=0, price3=0, price4=0;
}
void Counter::incrl1()
{
cout << "Enter num: ";
cin >> price1;
grandTotal += price1;
if(grandTotal>max)
overflow();
total1 += price1;
if(total1>9)
{
total1=total1-10;
total2++;
}
}
void Counter::incrl10()
{
cout << "Enter num: ";
cin >> price2;
grandTotal += price2*10;
if(grandTotal>max)
overflow();
total2 += price2;
if(total2>9)
{
total2=total2-10;
total3++;
}
}
I have obviously left out the other functions, but this should give you an idea.
as you can see if the total becomes>9 I am incrementing the next total, but this only works when it is less than 9 because otherwise it becomes 10 and that's not what I want and I can't figure out how else to do it. The only thing I can think of to solve the problem would be to call a function that has a long rediculous nested 'if' statement, but I feel there has to be another way!! Any suggestions would be much appreciated...thnks
