04 {
05 int gradeRange [4]= {0,0,0,0};
06 int mark = 0;
07 int counter = 0;
08
09 while (mark < 101)
10 {
11
12 cin >> mark;
13 if (mark > 100)
14 break;
15 if (mark >= 70)
16 gradeRange [3] ++;
17 else if (mark >= 40)
18 gradeRange [2] ++;
19 else if (mark >= 30)
20 gradeRange [1] ++;
21 else
22 gradeRange [0] ++;
23
24 }
25 while (counter < 4)
26
27 {
28 if (counter == 0)
29 cout << "0 - 29 ";
30 else if (counter == 1)
31 cout << "30 - 39 ";
32 else if (counter == 2)
33 cout << "40 - 69 ";
34 else
35 cout << "70 - 100 ";
36 for ( int i = 1; i <= gradeRange [counter] ; i ++)
37 {
38 cout << "*";
39 }
40 counter ++;
41 cout << endl;
42 }
