It helps to say which part you don't understand. May be reading the reply a
few times might help.

Is this what you have to do?
- Roll two dice. Sum the value (2 to 12).
- Record the number of times each sum turn out for a total of 10 rolls.
- ...?

As I said in the previous reply, the standard C++ headers are <iostream> and
<cstdlib> respectively. If your compiler doesn't have them, your compiler
is too old and non-conforming.
#include <iostream>
#include <stdlib>
#include <ctime> /* for time() function */
using namespace std;
Your course should cover namespace if your teacher expects you to use the
standard library.

Should be:
int main()

This is not the standard function. The standard way is:
srand((unsigned int)time(0));
> unsigned int c,a,b;
> unsigned int total[12];
Don't use magic number and you have to initialize the array to zero.
const int MAX_DICE_SUM = 13
unsigned int total[MAX_DICE_SUM] = {0};
> int max=13;
^^^^^^^^^^
Remove this.

const int MAX_ROLL = 10;
for (int i = 0; i < MAX_ROLL; ++i)

What do you want to do next? Print the count of the recorded sum or
calculate the percentage?

To print the result after MAX_ROLL:
for (int i = 1; i < MAX_DICE_SUM; ++i)
{
cout << "Sum " << i
<< " turn out " << total[i]
<< " times." << endl;
}
This is what I suggest you to do: Fire up your debugger and step through the
codes one line at a time to see how it works.
