Thread: I need some help!! PLEASE!!

I tried asking this on the c++ board but no luck.

here is my problem. I have a program that ask a user to enter some numbers it then will spit out the max and min and number of numbers he entered.

After that it will ask them if they would like to run the program again. If they choose yes how do I clear out the numbers the entered before.

ex: First run

Numbers Entered: 1, 2, -1, 9
-You entered 4 numbers
- Largest is 9
- Smallest is -1

Second Run:

Numbers Entered: 6, -8, 3, 5
- You entered 8 numbers //Should say 4
- Largest is 9 //Should say 6
- Smallest is -8 //This is right.


This is only my second program I have written so I am still a novice at this and can not figure out what to do. What is the code and where do I put it in this program?

#include <iostream.h>


int main()
{
const int MAX = 50; //Max size of array
int count = 0; //Counts # of items entered
int index = 0; //loop variable
int numbers_array[MAX]; //Array to store numbers
char ch = 'Y'; //Run again variable
int max; //Maximum Variable
int min; //Minimum Variable
int i = 0; //variable


do
{
while(ch == 'Y' || ch == 'y')
{

cout << "Please enter a number: "; endl;
cin >> numbers_array[index];
index++;
count++;
cout << "Please enter a number: "; endl;
cin >> numbers_array[index];
index++;
count++;
endl;
cout << "Do you want to enter another number?(Y/N) ";
cin >> ch;
}

min = numbers_array[0];
max = numbers_array[0];

while (i < count)
{
if (numbers_array[i] < min)
{
min = numbers_array[i];
}
else if(numbers_array[i] > max)
{
max = numbers_array[i];
}

i++;
}

cout << "You entered a total of " << count;
cout << " numbers." <<endl;
cout << "The largest number you entered was " << max << endl;
cout << "The smallest number you entered was " << min << endl;
cout << "Would you like to run program again?(Y/N)";
cin >> ch;
}
while (ch == 'Y' || ch == 'y');

return 0;
}


Thanks for the help! I dont knwo what the he!!to do!

not sure if this has been answered or not... and I'm not sure about how to do it in C++, but why not just reinitialize your array?

I think your problem is that you're not resetting your counters when running the request for numbers again... hence, you're just adding array elements...

you might just want to run through a loop in your array setting everything back to zero.. !? But I wouldn't recommend that method..
