Input/output for array

[Miele]

Hey,
So I've started learning C++ and I'm doing beginner excercises by Blitz Coder.
One of them is like that:

Write a program that asks the user to enter the number of pancakes eaten for breakfast by 10 different people (Person 1, Person 2, ..., Person 10)
Once the data has been entered the program must analyze the data and output which person ate the most pancakes for breakfast.

★ Modify the program so that it also outputs which person ate the least number of pancakes for breakfast.

★★★★ Modify the program so that it outputs a list in order of number of pancakes eaten of all 10 people.
i.e.
Person 4: ate 10 pancakes
Person 3: ate 7 pancakes
Person 8: ate 4 pancakes
...
Person 5: ate 0 pancakes

I'm only at the first part and I'm stuck.. I can't figure out what I'm doing wrong, because the user input is not being saved to the array :?

#include <stdio.h>

using namespace std;
int A[10];
int main()
{
int i=0;

    while (i<10)
    {
    i++;
    printf("Person number ");
    printf("%d", i);
    printf(" please insert how many pancakes you ate for breakfast \n");
    scanf("%d", &A[i]);
    }
    
    return 0;
}

If possible, don't complete the program, just give me few tips/hints..

And I'm gonna jump ahead - for second part of task, how can I find the person with least pancakes eaten in the array.
And how can I make order in the array for third part (going from biggest number to smallest?

Thank you all in advance!!

Firstly..

So I've started learning C++

but i see no c++ in your code.
http://www.cplusplus.com/doc/tutorial/basic_io/

for the least pancakes thing, define an int called 'least' and initialise to 1000 or some high number like that.
Then we you read in your number you can do something like:

int least = 10000;

// read in number

if(number < least)
{
   number = least;
}

So at the end of the loop that 'least variable' will have retained the smallest number.

When 'i' equals to 9, you're accessing A[10].

When 'i' equals to 9, you're accessing A[10].

Yes, I know that it starts from 0 and goes to 9 (for A[10] array)
But how do I store values in the array correctly?

[mutexe]

increment i after line 15 and change line 13 to

printf("%d", i+1);

that is if you want to keep using crappy C methods of course.

Mutexe, I didn't quite understoon the first reply that you wrote, could you specify it?
I fixed the first part. Thanks for that suggestion :)

morning,
I was only saying that you are using C-Style input/ouput constructs like scanf and printf, rather than the c++ 'equivalents' cin and cout.

the c-style stuff isn't that safe:

Technically, using namespace std; counts as C++, I guess. Of course, that's also a bad habit :P

[mutexe]

aye :)
