need help with compiling some simple lines of code

[james16]

code is below. compiling errors and warnings are at the bottom of the page. help is much appreciated.



1 #include <iostream>
2
3 using namespace std;
4
5 bool solver(int *input, int *checker, int length)
6 {
7 int j, k, l = 0, count =0;
8
9 //checking for repeated digits
10 for (j = 0, j < length, j++)
11 {
12 for (k = j + 1, k < length, k++)
13 {
14 if (input[j] == input[k])
15 return false;
16 }
17 }
18 //scans through the digits to check if the number is a run around number
19 while (checker[l] < 2 && count <= length)
20 {
21 //checker is a array thats been initialized to 0, if number is checked once, its value is 1 and 2 is it is checked twice
22 checker[l] += 1;
23 //since a number 147 is stored as 7 4 1 , checking goes from right to left, hence minus sign
24 l -= input[l];
25 while (l < 0)
26 {
27 l += length;
28 }
29 //count is included because for a 3 digit number max number of scan throughs for a runaround number is 4, with the first digit checked twice
30 count++;
31
32 }
33
34 if (checker[0] == 2)
35 {
36 return true;
37 }
38 else
39 return false;
40 }
41
42 int main(void)
43 {
44 int input[9] = {0};
45 int checker[9] = {0};
46 int number, i = 0, length = 0;
47 bool x = false;
48 cin >> number;
49
50 while (x == false)
51 {
52 // number++ for next greater number
53 number++;
54 while(number !=0)
55 {
56 input[i] = number%10;
57 number /= 10;
58 length++;
59 i++;
60 }
61 // if x is true, loop terminated and number is printed out, if x is false, check if next greater number is a runaround number.
62 x = solver(input, checker, length);
63 }
64
65 cout << number << endl;
66
67 return 0;
68 }

Can you repost this with code tags? With just a quick look you need to use the ";" character in the for loops not the "," character.

thanks alot man. that was the only error in the code. compiles fine now.
